Problems solved by technology

Due to the low calorific value of urban waste and the low content of combustibles, coupled with the influence of many factors such as seasons, the waste is unstable when it is burned, and auxiliary fuel needs to be added frequently to support the combustion, which affects the economic benefits and availability of the incinerator. The heat load of the grate of the furnace is limited, and the temperature of the incinerator is limited to 800-900°C, which leads to incomplete decomposition of harmful components such as dioxins during the waste incineration process, and also affects the effect of waste incineration

Embodiment Construction

[0010] Garbage pulverized coal composite combustion incinerator, as shown in Figure 1, it includes a feed hopper 1, a feeder 11, a fire grate 2, a slag outlet 5, a burner 3, and a steam drum 6, an air preheater 7. In the waste heat furnace 4 composed of economizer 8, the space above the waste incineration layer formed by the drying section 2-1, combustion section 2-2 and burnout section 2-3 of the grate is the pulverized coal combustion space 12, and the pulverized coal Install one or more low NO x The swirl pulverized coal burner 3 is made up of a primary air duct 3-2 and a secondary air duct 3-1. The pulverized coal is sprayed into the furnace by the primary air duct for combustion, and the secondary air duct supplements the required air for combustion.

[0011] When working, the garbage is sent to the grate 2 from the feeder 1 through the feeder 11, and after being incinerated by the drying section 2-1, the burning section 2-2, and the burnout section 2-3, the ash is discha...

Abstract

The invention relates to a kind of incinerator for coal compound burning, the character is that it combines the garbage grate firing method and coal firing method, the upper of the firing layer is coal firing space, there set one or more low Nox coal burner at the flank of the coal firing space.

Description

technical field [0001] The invention relates to a garbage pulverized coal composite incinerator, which belongs to environmental protection equipment. Background of the invention [0002] There are currently three ways of garbage disposal: sanitary landfill, composting and incineration. Among them, incineration treatment is an effective method widely used in industrialized countries, and it can maximize the reduction, harmlessness and resource utilization of urban waste treatment. Commonly used incinerators include mechanical grate incinerators, fluidized bed incinerators, rotary kiln incinerators, and thermal decomposition incinerators. Mechanical grate incinerators were developed earlier and have many forms. Their common feature is that they use layer combustion. , organize combustion on a mechanical grate in the form of mechanical ventilation. Due to the low calorific value of urban waste and the low content of combustibles, coupled with the influence of many factors suc...
