Abstract

The invention discloses a boiler furnace device which comprises a boiler furnace, wherein the upper part of the boiler furnace is a cuboidal furnace, namely, a dilute phase zone; the bottom of the boiler furnace is a conical furnace, namely, a dense phase zone; a water-cooled air distribution plate is arranged at the bottom of the conical furnace; a plurality of air caps are arranged on the surface of the water-cooled air distribution plate; a primary air compartment is also arranged at the bottom of the water-cooled air distribution plate, and the air caps on the water-cooled air distribution plate are communicated with a primary air inlet pipe; through holes in the air caps are used for introducing primary air from the primary air compartment; the conical furnace is also communicated with a secondary air inlet pipe; a wearproof layer is also arranged at the inner top of the boiler furnace; a membrane water wall is integrally arranged on the outer layer of the boiler furnace. According to the boiler furnace device, complete combustion of a biomass fuel is ensured, the combustion efficiency is improved, production of a large amount of nitrogen oxide is avoided, and the device also has the structural characteristic of the membrane water wall.

Description

technical field [0001] The invention relates to the technical field of biomass boiler equipment, in particular to a boiler furnace device. Background technique [0002] As we all know, a biomass boiler is a type of boiler. A boiler that uses biomass energy as fuel is called a biomass boiler. It can be roughly divided into biomass steam boilers, biomass hot water boilers, biomass hot air stoves, and biomass heat-conducting oil furnaces. Wait. [0003] During the use of existing biomass boilers: the existing biomass boilers are simple in structure (often using bulky refractory materials as the furnace wall), and often result in insufficient combustion of biomass fuel, and also tend to produce a large amount of nitrogen oxides (i.e. NOx). The increase of nitrogen oxides not only affects the combustion efficiency of the boiler, but also brings great difficulty to the subsequent tail gas treatment. [0004] Therefore, how to overcome the above-mentioned difficult problems in t...
