The invention discloses an energy efficiency evaluation method for blending combustion of biomass in a coal-fired boiler. The energy efficiency evaluation method comprises the following steps: acquiring coal types and biomass for blending combustion in the coal-fired boiler; acquiring flue gas temperature and flue gas components at an outlet of an air preheater of the coal-fired boiler during blending combustion, and primary air temperature and secondary air temperature at an inlet of the air preheater; obtaining SO2 concentration, NOx concentration, smoke dust concentration and heavy metal concentration at a chimney inlet flue of the coal-fired boiler during blending combustion; according to the flue gas temperature, the primary air temperature and the secondary air temperature, the boiler heat efficiency during coal type and biomass blending combustion is determined; and determining a boiler emission evaluation result during coal type and biomass blending combustion according to theSO2 concentration, the NOx concentration, the smoke concentration and the heavy metal concentration in combination with flue gas components. The technical problem that no evaluation method for the influence on the boiler efficiency and the environmental protection system after biomass blending combustion exists at present is solved.
Description
technical field [0001] The present application relates to the technical field of analysis of coal-fired boilers, in particular to an energy efficiency evaluation method for coal-fired boilers mixed with biomass. Background technique [0002] With the development of science and technology and people's emphasis on the ecological environment, the energy supply structure is facing changes. The replacement of traditional energy with new energy and the replacement of fossil energy with non-fossil energy are the mainstream of change today. [0003] Biomass fuel has the characteristics of high water content, complex components, low energy density and scattered distribution. The development of biomass can improve the world's primary energy structure, alleviate the contradiction between energy supply and demand, reduce greenhouse gas emissions, and protect the ecological environment. Blending biomass in coal-fired boilers is an effective way to efficiently utilize biomass resources. ...
