Furnace combustion gas cooling device artistry to make improvements: new gas furnace wall cooling apparatus of the present utility model relates to ammonia and methanol production technology in the field of coal as raw material gas, in particular furnace means for fixed layer intermittent gas . Efficient and environmentally friendly gas furnace in innovation is mainly reflected in, 巩义富 China machinery by developing secondary use of flue gas recovery system. Its main ingredient is hydrogen, carbon monoxide and light hydrocarbons. Single-stage gas ignition temperature of between 500 ℃ -600 ℃, mixed with air into a furnace after certain percentage, a fire will explode. Therefore, the production and distribution of gas in the process, once the explosion occurred, often causing huge casualties and property losses, so the practical implementation of fire safety design gas station is very important. For gas production is less than 6000 cubic meters / hour of a small gas station, "gas station design specifications" in the provisions of the workshop with adjoining gas users, but it should set up a firewall. Fire spacing aspect. Under the "architectural design code for fire protection" GBJ16-87, the gas plant and the adjacent gas station should meet the fire spacing of 10m, and civil construction should meet the fire protection distance of 25m. Here's no spacing requirements except for the direct use of the gas furnace gas and adjacent exterior wall firewall workshop in terms of non-gas users should still meet fire pitch workshop of 10m. Gas furnace dust safety instructions and sub-pipelines: Because the furnace occurred in the normal course of small and medium gas and dust in the seal has been removed communicating directly with the gas pipeline, in case of failure, by sealing the gas pipeline is to Emergency water filter to achieve, if operational errors, easy to form a negative pressure air very easily inhaled, and cause an explosion. "Gas furnace design specifications" GB50195-94 provides only installed on the electrical filter and scrubber burst valve. But I believe that in addition to the above two points should be at the end of the filter and piping installation of explosion-proof film. So as to be in the line of venting gas does not stay dead, thus effectively reducing the chance of tempering caused due to gas pipeline explosion. And also at the top end of the gas furnace, gas outlet of the gas mains and an additional charge of relief tube. Sampling should be located on the diffuse nozzle in order to facilitate the maintenance purge gas furnace pipes, gas detection content. The diameter of the vent pipe is determined based on the volume of the furnace, if the volume is greater than or equal to 1 cubic meter, vent pipe should not be less than 100 mm; if less than 1 cubic vent pipe should not be less than 50 mm. Because the gas in the furnace and the high-pressure pipe is in charge of maintaining the track and is provided with a vent pipe, easily leak. And furnace stoker coal and the ash is to rely on the lock hopper and ash lock hopper to close the high-pressure gas furnace, high pressure gas shall release the lock hopper can be, once operational errors Mifengbuyan or two-stage gas stoves, gas will be ejected, easy to form an explosive mixture. So in this part of the electricity lighting and power should remain with explosion-proof design and additional CO gas alarm, in order to better meet the fire safety. Advantages furnace gas process heating effect of gas: The following are the three major advantages of gas furnace gas from the perspective of saving energy, reducing costs, the direct combustion of coal and the use of coal gasifier gas is made to do In contrast, if it reaches the same heat, the direct combustion of coal used in coal gas furnace than with the coal into gas in coal used to be more. Therefore, the use of gas stoves can save not only coal, but also achieve better thermal effects. Gasifier based on coal as raw material to produce gas. The raw coal furnace was added, after high-temperature heating fuel by the bottom, and the bottom of the gasifying agent into the physical and chemical reactions occur, resulting in a crude gas. Crude gas and then after dust directly for combustion equipment. Human use gas stoves have a hundred years of history, it is a very mature gas technology. Now the gas furnace has been carried out in favor of environmental protection technological transformation in the traditional gas process has also joined the process of coke, dust, water addition, so that the resulting gas is not only clean, generate less waste, but also reduce pollution.
