Abstract

The invention discloses a cooling ventilation device of the fire grate piece in the compound expression fire grate system, all fire grate has interaction overlap to become the slope fire exhaust, the air outlets (26)have established in the moving grate piece (14, 16, 18) and the fixed fire grate piece (13, 15, 19), the fire grate system has divided into dry section (A), hot region (B), burn cinders section (C), the height fall exists between each section, the unaided once-wind chamber (6, 9, 12) has separately established underneath of the dry section (A), hot region (B), burn cinders section(C). The invention favors the trash combustion of the stove in the turbulent state. Fire grate piece has cooled to even, the ash dregs is not easy to stop up the gusty area, can penetrate the close trash material level with high moisture content, the trash has short drying time, realizes trash material level evenly, stable, full dry and combustion.

Description

technical field [0001] The invention belongs to a grate piece cooling and ventilation device of an incinerator grate system, a key component used for solid waste incineration treatment. In particular, it relates to a composite grate incinerator primary air supply device for the grate system of the incinerator of municipal solid waste. Background technique [0002] The most important component of a waste incinerator is the incineration grate system. Waste incineration usually proceeds in three steps, namely "drying", "incineration" and final conversion into "slag". The incineration grate system is responsible for the transportation of garbage in the furnace, and at the same time improves the mixing and disturbance with the air to improve the combustion efficiency. [0003] There are now various types of incinerator grate systems available on the market, in particular so-called reciprocating incinerator grate systems. The grate pieces in the form of a reciprocating grate ar...
