Thermophysics and Thermal Power Engineering| Summary: | The paper was consider the influence of the replacement of part of coal dust by pyrolysis gases on ecological and technological operational parameters of TPP 312 boiler during its operation at low loads. The following values of boiler loads 210, 190, 170 and 150 MW were taken into account. The part of biomass pyrolysis products in the heat balance of the boiler was taken in 10 and 20%.
It was found that when feeding pyrolysis products of biomass with primary air evenly through all burners in operation, there is an increase in heat flow through the bottom of the furnace and it is possible to expand the lower limit of the boiler to a load of 170 MWe.
The substitution of coal for biomass pyrolysis products does not reduce the generation of nitrogen oxides. On the contrary, there is a slight increase in the emission of nitrogen oxides with an increase in the part of pyrolysis gases for boilers loads of 210…170 MWe. |
