coal boiler capacity tons h
Select the appropriate coal boiler capacity tons h fuel and combustion forms: the most consumed fuel in use is the boiler, energy-saving measures to do first of all have to start from the choice of fuel. In the current economic conditions, there are three main boiler fuel, namely the solid fuel, liquid fuel and gaseous fuel, three different heat generated by the fuel which is not the same, the degree of harm to the environment is not the same. On the whole, in terms of heating fuel gas quality or environmental protection has a significant advantage in the choice of fuel should be preferred. Heating boiler in some systems because of the influence the production process and the fuel supply capacity, the choice of gaseous fuel is also subject to certain restrictions. In the selection of fuel, because the high cost of this choice of fuel in the boiler heating costs tend to be higher. Is more feasible briquettes may be employed, it will be used after vaporization, the residue after burning so that less amount of the exhaust gas is small too heavy discharged from the combustion, and the combustion heat value of the coal after vaporization is relatively high, so the use of more cost-effective in the heating boiler.
Factors which influence energy-intensive industrial coal boiler capacity tons h energy-intensive industrial boilers factors influencing factors which have high energy consumption of industrial boilers which have 1, energy consumption is low management level industrial boiler is too large, are long-term presence of many companies in the current . On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.
Analysis of Gas coal boiler capacity tons h heating and energy issues: In recent decades, China's production and consumption of energy, the proportion of coal accounted for more than 70% of coal-based energy and heat sources caused serious air pollution in our country. In recent years, with the national emphasis on environmental protection as well as the determination of the fog and haze governance perspective, the energy structure adjustment, the gradual transition from coal to oil, gas and other cleaner fuels. Use of industrial boilers has been raised from the gradual transformation of coal-fired boiler or gas boiler replaced. Therefore, to improve gas efficiency, reduce dust pollution, to achieve clean combustion, is an important research topic, promote the use and development trend of gas-fired boiler has also been overwhelming.
March 11, we learned from the Harbin municipal government: Harbin win the 2019 New Blue Sky Battle embodiments released this year, Harbin will be coal-fired pollution control, pollution discharge standards, high Vehicle emission control, comprehensive improvement of urban and rural non-point source, and prohibiting straw utilization as the main direction, precise Shi policy. Strive to the end, so that the sulfur dioxide, nitrogen oxide emissions are reduced by more than 17.6% in 2015 and 20%; concentration of PM2.5 decreased to 52 micrograms / cubic meter or so, and strive to 50 micrograms / cubic meter or less; and more severe reduce the number of pollution days to 21 days or less.
After the proposed scheme, Harbin bulk coal strengthen management and control, strengthening coal quality testing, to improve the sampling frequency. This year will develop clean heating embodiment, the priority development of the city urban central heating; central heating covered areas being difficult to accelerate the implementation of natural gas heating and electric heating, and other distributed clean heating. Unit embodiment "coal to clean energy" should be synchronized removal of coal-fired boiler, gas boiler need replacement after low NOx combustion technology, clean heating rate of 60% or more. City buses, taxis or car clean energy proportion of new energy and strive to reach 94% and 80%. Promote the use of gas vehicles to achieve the national emission standards for six. Six to stop selling below the country's gasoline and diesel. Establish responsibility dust control system, built-up areas prohibit the construction site mixing of concrete, mortar and use of bagged cement 9 city and county (city). Under the premise of protecting people's livelihood, heating boilers should be relatively conducive weather conditions during the pollutant dispersion from the oven, in the same area by different heating boiler early in the evening three periods of peak load shifting from the furnace.
