What is the main difference between a coal-fired boiler and a gas-fired industrial coal biomass fuel steam boiler? Nominally, the obvious difference between a gas-fired steam boiler and a coal-fired boiler is that the fuel used is different. The former uses natural gas and the latter uses coal. I think the misgivings of many boiler users are why they should eliminate coal-fired boilers because many have already purchased and used coal-fired boilers. If they switch to gas-fired boilers, it will be a huge expense. Firstly, according to the development direction of China's ecological environment, coal-fired boilers will gradually be replaced by gas-fired boilers or other clean and environmentally friendly energy boilers, and gradually withdraw from the historical stage. Yes. The difference between coal-fired boiler and gas-fired steam boiler is very big, and the main reason for eliminating coal-fired boiler is environmental protection. From the fuel supply part, the gas-fired boiler only needs a pipe to connect to the boiler; the coal-fired boiler requires coal yard, coal (belt or man-made), coal transport, loading and unloading, storage and boiler loading process. It will produce dust, causing serious pollution to people's living environment. From the point of view of atmospheric emissions, the content of dust in natural gas is very small and can be negligible; the ash content of coal is high, and the ash content is about 10% and 30%, which will produce smoke after combustion. If dust removal facilities are reduced, pollutant emissions will be reduced. It will increase; if there are more dust removal facilities, the corresponding costs will increase, which is not a long-term solution. In addition, the sulfur content of natural gas is also very small, coal-fired boiler dust removal, desulfurization and nitrogen removal can be obtained, gas-fired boilers only need to consider the problem of nitrogen removal. From the point of view of other waste emissions, natural gas is basically free of other pollutants, especially urban gas. In the case of coal, coal yards, especially small boilers built mainly in the open air, will produce coal slurry water during the rainy season, seeping into groundwater or sinks. When entering the surface water, the burning ashes are transported to produce dust. Of course, there's a difference in other ways. Different. For small-sized boilers, gas-fired boilers are more energy-saving than coal-fired boilers, with simple equipment flow, small footprint, low operating and maintenance costs, and so on. These are the main differences between coal-fired boilers and gas-fired steam boilers, and the significance of eliminating coal-fired boilers. It can be seen that the use of gas-fired boilers is the general trend of the whole society.
The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.
Necessity textile mill converted to a coal-fired boiler gas boiler is a boiler equipment industry needs is more important, because a lot of links to the papermaking process requires a lot of steam drying, stereotypes and so on. However, along with the national policy of environmental protection departments to ban coal-fired boilers, and now more and more manufacturers have to use coal-fired boilers to coal-fired boilers upgrading or purchasing a new low - NOx emissions. Mills from coal to gas boilers is an important direction of the current transformation of coal-fired boilers, is one of more types of enterprise transformation, especially in the area more natural gas, coal into gas boiler is the main way. 1, in order to transform mechanization layered fired boiler gas boiler, you should first remove the front arch and a rear arch, while increasing the bottom heating surface, instead grate, grate to prevent overheating, combustion; 2, through the furnace heat transfer calculation methods determining the size of the boiler, furnace flame center position, and then pouring furnace work. In order to avoid the center position after arch boiler tubes, based on the original slope of the original arch made pipe. 3, the furnace in order to prevent an explosion, when the coal-fired boiler furnace gas is substituted, or when fuel not atomized combustion gases in the furnace incomplete combustion or heating surface of the end of the furnace, a fire or explosion occurs, should be mounting the appropriate parts of the boiler explosion vent, and to increase the ignition and flame failure protection program control to automatic control means, to ensure safe operation of the boiler. 4, is closely related to the selection and arrangement of the burner and furnace, the filling degree of the flame in the furnace should preferably not to form a dead air. Gas burner arrangement considered reasonable and piping layout, convenient operation, inspection and maintenance;

2, the region west of Seven Road, Sheung Tak Road, west along the eight dining pollution checks to ensure that all food and beverage outlets normal use of fume purification facilities, and urge all stores on a regular basis to do routine maintenance.
The biomass and coal are combusted simultaneously. When it is used as a supplemental fuel in an existing coal boiler, biomass can provide the following benefits: lower fuel costs, avoidance of landfills and their associated costs, and reductions in sulfur oxide, nitrogen oxide, and greenhouse-gas emissions.Learn More
