Abstract: Our country is a big agricultural country, and has very rich biomass energy, such as wheat straw, straw, corn straw and so on. These biomass energy in the process of combustion will emit a large number of polluting gases, but these gases and coal-fired boiler emissions are different. This paper uses the method of experimental analysis to compare and analyze the characteristics of particulate matter emission from biomass boiler and coal-fired boiler. The experiment shows that there are great differences in particulate matter emission from these two combustion methods.
Biomass boiler refers to the boiler with biomass energy as fuel. In this paper, in order to compare the characteristics of biomass boiler and coal-fired boiler emissions, two boilers with different structures are designed to carry out the test. Biomass energy uses straw and wood. The characteristics of particulate matter emissions are analyzed through the combustion of bioenergy, and the characteristics of particulate matter emissions from coal-fired boilers are compared, and the differences between the two are finally obtained.
I. Select research objects
(a) Boiler selection
At present, biomass boilers are specially designed for burning biomass energy boilers, and there are also boilers modified on the basis of coal-fired boilers [1]. In this experiment, two biomass boilers with different forms were selected, one of which was a coal-fired boiler with similar energy quality to the biomass boiler. All three boilers operate in intermittent mode, limiting the burning time of the three boilers to about 10 hours during the entire heating period. The specific parameters and indicators of these three boilers are analyzed as follows:
