The coking plants in the metallurgical sector also produce gas, but these gases are basically used in metallurgy and metal processing. There is no spare capacity to supply gas to other departments. Moreover, the distance is quite far, so gas transmission pipelines with good sealing must be laid.
Carrying out long-distance gas transportation and manufacturing gas tanks to store gas... time travelers have not yet reached this industrial level. Therefore, the starting point of the industrial and agricultural gas stove designed by Wang Luobin is to be able to utilize gas on site.
Wang Luobin had a lot of information on gas stoves at hand. There was especially a lot of information on local gas stoves, which were colorful and full of whimsical ideas. But he did not trust these materials. Local gas stoves blossomed everywhere during the Great Leap Forward era.
It's all over the place, and the movement is over without leaving any trace. Obviously there are problems in terms of economy, safety and practicality. He used to live in a rural area and has experienced numerous similar "technology promotions", such as biogas digesters and soil solar energy.
Zao... In the end, they either disappeared or were half-dead due to various reasons.
It can be seen that the promotion of a new technology must take into account many factors, and the most important ones are practicality and economy. Both are indispensable.
Therefore, in the selection and structural design of the gas generator, he discarded many things that were too "local" and tried to be as "modern" as possible within the scope of the time traveler's industrial capabilities to ensure that it could be used effectively.
.
He chose a flat-suction circular furnace for the food processing plant, with a diameter of 1.5 meters and a height of 3.5 meters. It uses a blower to blow the air. This kind of furnace has a larger furnace, even air and fuel distribution, and high gasification intensity.
It can gasify 60 kilograms of coal per hour. The required materials: refractory bricks, red bricks, cement and cast iron, which can be provided by the industrial sector. The sealing method uses water sealing, which is simple and safe. The most difficult thing to make is nothing more than a reverse flow stop valve -
―This is a cast iron piece, so there is almost no difficulty.
After the gas is produced, it is first removed by a brick cyclone dust collector, and then washed with water to remove tar and dust. After cooling, the clean gas generated is used by the diesel engine. The sewage used for water washing contains a large amount of tar and is collected by the chemical industry department.
Carry out recycling processing.
A high-power steam generator is also installed in the furnace. When the fuel is gasified, the heat of the gasifier is used to burn steam. This also solves part of the demand for steam in food processing plants.
In order to facilitate ventilation and avoid carbon monoxide poisoning, the gas furnace is built under an open work shed. The gas generator, blower, and diesel engine are integrated into a power workshop. The gas-driven diesel engine drive belt drives the horizontal shaft for transmission. All kinds of machinery and equipment only need to connect the flywheel
The belt on the machine is connected to the horizontal shaft and can be driven. This Changchai 22-horsepower engine is enough to meet all the power needs of the food processing plant - including the needs of the blower to keep the gas stove running.
The furnace was successfully ignited after it was built, and the fuel used was coal from Leizhou. After Leizhou Sugar Company won the Sugar War, they continued their efforts and took advantage of the great opportunity of Master Zhu’s family being killed to directly annex Master Zhu’s shipping company.
In addition to transporting sugar to Guangzhou and Lingao, more than a dozen large ships also transport coal - all of which Chang Shide sent people to purchase from the local area and neighboring Gaozhou, Lianzhou and other places. This kind of coal is relatively inferior.
It is suitable for gasification.
Another advantage of the gas stove is that the requirements for the stove are not high, and there is no need to talk about any skills. All you need to do is strictly follow the regulations. The work of adding fuel is not heavy, unlike burning a boiler, which requires adding coal all the time. Wu Nanhai
So I selected an old man in his fifties from the semi-labor force of Bairen Commune to take charge of this matter. Although he looked very old, he still had strength, was sharp, and was not confused.
When the gas stove was ignited, Wang Luobin personally started the diesel engine with a hand rocker. The diesel engine crackled a few times and then started running "chugging". It felt the same as when using diesel.
Wang Luobin used the gas stove in the food processing factory as a demonstration sample of gas stove
Huang Dashan admires the gas furnace project very much - gas has a high calorific value and stable heat generation, which is very beneficial to temperature control. To carry out fermentation and enzymatic decomposition, the temperature requirements are quite stringent.
The gas stove in the food processing plant has greatly eased the consumption of biogas produced on the farm. Originally, this was a large consumer of farm biogas. The biogas production of the biogas digester is very unstable. One of Wu Nanhai’s biggest problems is that the biogas digester is not built.
Quite a few, but no matter how well-designed the pool is or how large its capacity is, the problem of reduced air supply will occur from time to time, and sometimes the air supply will suddenly stop. Fuel must be urgently called to replenish it.
Wang Luobin personally looked at the stove for a long time, observing the combustion situation. After feeling that everything was normal, he then told Mo Xiaoan: "Hang up bird cages in this shed and several nearby workshops and raise a few birds."
“What do you do with birds?”
"Be an alarm to avoid carbon monoxide poisoning." Birds have much less tolerance for carbon monoxide than humans and can warn of carbon monoxide leaks.
"No need. The smell of gas leakage is so strong, it's impossible not to smell it..."
Wang Luobin glanced at the Minister of Light Industry: "Carbon monoxide is colorless and odorless. The smell is added."
"I understand, I understand." Mo Xiao'an sweated - this was not a fool's embarrassment on the spot, "I'll make arrangements right now."
Wang Luobin walked around the food factory again - he now has an important task to make an estimate of the energy usage of the time traveler, so as to make overall arrangements for the various prime movers and energy sources currently used to improve their utilization efficiency.
The majority of the prime movers currently used by the Cross Cross Group are electric motors, which rely on two power stations and sporadic wind turbines for power supply.
Electric energy is clean and convenient to use, and electric motors work stably, so they are naturally the best choice for prime movers. However, the Industrial Energy Commission believed in an internal evaluation that electric motors and various power-related equipment, including generators, transformers, transformers, cables...
Self-production is very difficult - this difficulty is mainly reflected in the materials. In particular, the magnetic steel sheets used in electric motors are far from being manufactured by ordinary local methods. With the industrial capabilities of Chuan Chuan Group, manufacturing equipment is not difficult.
The difficulty is that raw materials can only be used as reserves, and there will be no replenishment after they are used up. Considering the need to replenish damaged and repair equipment, these materials and parts must be kept in a certain amount. Before these problems are overcome,
Electricity is obviously not the main development direction.
Next to the electric motor is the steam engine. This type of machine has been gradually promoted in various places since the machine factory put into mass production the 50-horsepower Mozi II model. The steam engine is the least efficient and has low technical content. Various types of boilers can be used
This kind of fuel is the main source of power for traversers in the recent stage.
As for diesel engines, gasoline engines, etc., they rely on stored petroleum fuel. Now that they are gradually "gasified", they will have a wide range of application prospects. Although the output power of their internal combustion engines is relatively small, they are small in size and light in weight.
, with the advantage of being easy to move, it is much more convenient to use than the heavy steam engine + boiler power combination. The gas generator can be large or small, the configuration is flexible, and the demand for fuel is not high.
Promoting gas generators is only one part of this plan. Wang Luobin also plans to improve fuel efficiency through deep processing of fuel and modification of combustion devices.
There are many types of fuel used in the journey. Apart from the fuel oil and the biogas produced by the biogas digester, the largest fuel is coal. It is indispensable from the boiler of the steam engine to the canteen for cooking. The second is
Various wood scraps, sawdust, straw, etc. The calorific values of various fuels are different, and their use is also very extensive. Wang Luobin proposed in the plan to change the past practice of haphazard and unstandardized fuel distribution and instead establish a fuel
The factory, in addition to biogas, preprocesses various fuels in a unified manner and then uses them by various departments.
This fuel plant will temporarily set up a simple coal processing workshop and at the same time receive the original wood retort kiln.
The coal processing workshop is responsible for washing the coal shipped from other places. The coal shipped from Hongji and Guangdong is mined by local methods. It is mixed with a large amount of impurities, and the quality of the coal is also different. The internal ash content is small and the internal content is small.
Coal with high ash content is mixed together and thrown into the boiler for combustion indiscriminately, which will cause a lot of waste.
By washing coal, impurities in raw coal are removed, and then high-quality coal and low-quality coal are simply classified. Gangue is removed. Coal is crushed according to its purpose, which can greatly improve the efficiency of coal use.
Wood fuels, except for sawdust and materials that cannot be retorted, are no longer directly burned. Instead, they are retorted into charcoal in a retort kiln to improve combustion efficiency, reduce pollution, and recover wood tar. The waste heat of the retort kiln is used in an evaporator to produce steam.
Provided to Bopu's factories for use.
In addition to coking coal, fuel coal and charcoal are uniformly converted into standard coal units and supplied to various departments for use in order to accurately calculate the fuel usage of each department.
The use of rice straw and rice husk fuels is under the control of the Agricultural Committee. Wang Luobin does not recommend using rice husk as fuel for the time being - it contains a large amount of silica and is very polluting when burned. Special equipment is required to use it as fuel.
can be used effectively.
Regarding the many stoves currently found in canteens, factories and even dormitories, in addition to biogas stoves, Wang Luobin decided to conduct a comprehensive inspection and registration, unify stove types, dismantle simple stoves that do not utilize fuel and heat energy well, and at the same time forcefully promote the use of briquettes.
The manufacturing technology of honeycomb briquettes is simple. Use the fuel plant to screen the coal at the bottom, grind it once, mix it with loess in proportion, and use a simple hand-operated briquette machine to make it. Two or three workers can make several thousand a day.
