Integral process and equipment of garbage fuel synthesis and burning generation

Abstract

An integral process of synthesizing garbage fuel and incinerating it to generate power includes preparing garbage made fuel by process of grinding, drying, magnetic selecting, modifying, mixing and pressing; sending prepared garbage made fuel into boiler to burn it for generating power; using boiler tail fume and steam of steam turbine in preparing course of garbage fuel to provide heat source being used in drying unit and modifying unit in preparing course of garbage fuel.

Description

technical field [0001] The invention relates to an integrated process and equipment for garbage fuel synthesis and garbage high-efficiency incineration for power generation. Background technique [0002] High-temperature incineration technology is an effective method for waste disposal, especially for urban waste with relatively high calorific value. After high-temperature combustion, the volume of waste can be reduced to less than 1 / 5 of the original, killing pathogenic bacteria, and can recover heat for heating and Power generation, so it is adopted by many countries. At present, domestic waste incineration mainly adopts direct incineration, that is, municipal waste is directly put into boilers for incineration after simple pretreatment. The boilers are mainly grate furnaces, and some use fluidized bed boilers. However, since the calorific value of general urban waste is about 1000kcal / kg, and the water content is about 50%, resulting in low combustion efficiency and poor...

Problems solved by technology

However, if the production process uses the heat energy generated by the direct combustion of fuel as the heat source required for the production process, the production cost is expensive
