coal fired boiler efficiency calculation

This time, the party quickly staff also two school children brought nearly this reading materials, together with the 2017 contributions, a total of two school books donated more than 3000, to add more color to the world of children. Fang fast philosophy tells us that the work should be "fine industry", Jingye is to "+ dedicated professional", it requires us to "long-term focus and become an expert." Shu ten years, a hundred years trees, love must not be "superficial", and to focus on "little", and stick to it. This down a few years later, bit by bit we will help to gradually bear fruit, harvest fruit.

Biomass coal fired boiler efficiency calculations, Henan gas boilers, coal-fired boilers contrast due to environmental pollution problem is serious, the national intensify pollution, especially coal-fired boilers because of incomplete combustion, low thermal efficiency, high pollution emissions, become the primary target of the boiler regulation . Coal-fired boilers due to the low initial investment cost by the majority of enterprises of all ages, in fact, in many ways the point of view, coal-fired boiler is not the best choice. 1, the beginning of investment costs: inputs from the perspective of initial purchase of the boiler, the same tonnage boilers, gas boilers generally highest in Henan, followed by biomass boilers, coal-fired boilers finally. 2, operating costs: the operating costs in terms of the highest Henan gas boiler, followed by coal-fired boilers, biomass boilers and finally, the price of gas prices in various regions are not the same, but much higher than the biomass and coal, biomass price and coal price difference is not big, but because of the low thermal efficiency of coal-fired boilers, coal-fired boiler running costs are higher than the biomass boiler. 3, environmental protection: From the environmental point of Henan gas boiler is undoubtedly the most environmentally friendly, followed by biomass boilers, coal-fired boiler is again. Henan gas boiler fuel is natural gas, biomass fuel boiler is biomass or biomass particles compact, emissions of coal-fired boilers is the largest. 4, Application areas: geographically speaking, Henan gas boiler apparently allow the use of any region, but due to the uneven gas supply, even in some places did not open the gas pipeline, this time biomass boilers to be the best choice, because biomass fuels is still relatively environmentally friendly, because biomass is processed from agricultural and forestry waste such as sawdust or straw fuel. As for coal-fired boilers, in some areas has been limited, it does not allow installation of a coal-fired boiler, due to the different areas of environmental protection standards are not the same, allowing the use of what kind of boiler main contact your local EPA shall prevail.

Applicable fuel: coal, biomass, coal mixed with biomass

Circulating fluidized bed boiler application:

Henan reasonable control of gas-fired coal fired boiler efficiency calculation flue gas oxygen content from the actual point of view, in the Henan gas boiler combustion, the oxygen content of the flue gas reasonable control, can also reduce fuel waste to a certain extent. Technology is adding a control loop combustion control system, the main function of this control loop is a variable flow rate and the ratio of the combustion air flow rate control, such a control system, also known as closed loop control system of flue gas oxygen content. By using this control system, making Henan ensure the most economical gas-fired boiler burning throughout the production process. From a practical point of view this stage, the oxygen content is more commonly used in the flue gas. Therefore, it can be said, in Henan gas boiler combustion process by adding a control loop to further improve the reasonable control of the flue gas oxygen content, this method is relatively simple technology, and have a certain economy. Flue gas oxygen content control to the actual operating status of the boiler ignited, under different operating circumstances, to rationalize the ratio of flue gas oxygen content, so that as far as possible both to meet the needs of Henan gas boiler combustion, while there reduce energy consumption. Through the above analysis, we know Henan gas boiler in the actual work process, by controlling the oxygen content of the flue gas in order to achieve energy-saving operation. As people focus on air pollution, the community calls for energy saving technology is growing. In this case, the promotion of energy-saving technologies and upgrading gas boiler, it is very urgent. The relevant state departments should proceed from the actual situation, efforts to promote coal to gas projects, the implementation of the relevant environmental protection policies as soon as possible, give full play to the advantages of gas-fired boiler in terms of energy saving, thus making a contribution to our energy conservation.
