Biomass solid fuel boiler for electric power generation

Abstract

The invention relates to a biomass solid fuel boiler for electric power generation. The biomass solid fuel boiler comprises a boiler, wherein the boiler comprises a water chamber, a combustion chamberand an ash chamber; a feeding port is formed in one side of the combustion chamber; a leakage net is arranged at the bottom of the combustion chamber; a smoke return pipe is arranged at the other side of the combustion chamber; the upper part of the smoke return pipe is divided into a first smoke pipe, a second smoke pipe and a third smoke pipe from top to bottom; a first gas pump is arranged onthe first smoke pipe; a second gas pump is arranged on the second smoke pipe; a third gas pump is arranged on the third smoke pipe; a water inlet pipeline is arranged at one side of the water chamber;zigzag partition boards are arranged in the water inlet pipeline; a water pipe is arranged at the other end of the water inlet pipeline and communicated with a water tank; an one-way valve is arranged in the water pipe; a driven wheel is arranged in the ash chamber; an ash board is arranged outside the ash chamber; an electric wheel is arranged on the ash board; and a conveyor belt is arranged onthe electric wheel and the driven wheel. The biomass solid fuel boiler is compact in overall structure, high in heat energy converting rate and convenient to manage.

Description

technical field [0001] The invention belongs to the field of mechanical heat energy, in particular to a biomass solid fuel boiler for electric power generation. Background technique [0002] Biomass solid fuel belongs to renewable energy and has broad development prospects in the energy field. Biomass fuels such as straw often produce harmful gases such as carbon monoxide due to insufficient combustion during the combustion process. At the same time, biomass fuels cannot be completely burned, which will also cause energy waste. Therefore, the energy conversion rate has become one of the important indicators to measure thermal energy equipment. In addition, incomplete combustion of biomass fuel will also produce a lot of smoke and dust, once discharged into the air, it will cause serious pollution. The current biomass solid fuel boilers for electric power generation have a relatively loose land occupation structure, many pipeline distributions, and a large area, which is no...
