Formula and preparation method of garbage derived fuel block additive

Abstract

The invention discloses a preparation method of a garbage derived fuel block additive. The method comprises the following steps: mixing coal powder and potassium permanganate, and sufficiently mixingwith cotton rope fibers to prepare an ignition cotton rope; mixing coal powder and potassium permanganate, and fully mixing with sawdust to prepare an ignition agent; mixing coal powder and potassiumnitrate to prepare a mixed combustion improver; fully mixing loess powder and lime powder, and adding aluminum oxide powder to prepare a loess powder mixture; and fully mixing the ignition cotton rope, the ignition agent, the mixed combustion improver and the loess powder mixture to obtain a garbage derived fuel block additive. The invention also provides a formula of the garbage derived fuel block additive. The garbage derived fuel block additive has the advantages of stable heat value and rapid combustion, and can solve the problems of low garbage incineration efficiency and excessive pollutant emission.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a formula and a preparation method of a refuse-derived fuel block additive with stable calorific value and rapid combustion. Background technique [0002] Due to poor front-end classification of domestic domestic waste, the composition is complicated. Most of the high-quality plastics inside, such as plastic bottles, PE plastic bags, cans, etc., have been picked up by waste pickers. All kinds of kitchen waste and liquids, etc., are of poor quality and have various components, so they are not suitable for recycling (plastic recycling and granulation). However, if it is used for direct incineration, a large amount of pollution will be generated due to the structure of the combustion furnace and the characteristics of the process; due to the high moisture content of the plastic, the unstable calorific value, and the impurity components have not been effectively removed, etc., resulting in burning ...

AI Technical Summary

Problems solved by technology

[0006] 1. The fuel has a high calorific value, normal natural combustion, insufficient oxygen supply, incomplete combustion, and a large amount of intermediate products

Transitional oxygen supply results in increased energy consumption and greater loss of furnace temperature;

[0007] 2. There is a lot of moisture, so it is not suitable for drying. The problem of moisture affecting combustion will increase, resulting in energy loss

[0008] 3. The temperature of the furnace is difficult to control stably, the pure plastic has a high calorific value, and the temperature of the single product is high, the equipment is unbearable, and the gas composition is complex and uncontrollable;

[0009] 4. Material transportation, storage, and transportation are affected by various shapes, materials, and impurities of mixed plastics, and there are many inconveniences;

[0010] 5. The plastic is easy to shrink and decompose when heated initially, and there is gas pollution;

[0011] 6. The combustion of chlorine-containing plastics is easy to form dioxin, hydrogen chloride and other substances, which are highly toxic and polluting, and corrode equipment;
