Abstract

The invention discloses a slight fuel accumulation ignition increasing mechanical feeding method. The slight fuel accumulation ignition increasing mechanical feeding method comprises the following steps of: feeding a light biologic material or a fine powder fuel or recycled material fine powder on a negative pressure position in a boiler furnace, utilizing a boiler with a certain pressure and using a primary or secondary air special organization to form a special burning zone with accumulation and afterburning action, prolonging retention time of the light biologic material or fine powder fuel or returning fine powder on a secondary furnace bottom, and combining characteristics of different fuels. The technology can effectively solve the technological problems that the light biologic material or the returning fine powder can cause lower burning efficiency or higher water containing light fuel such as light weight straw, a plastic film in garbage and high fine powder bunker coal, and the slight fuel accumulation ignition increasing mechanical feeding method has the advantages of effectively improving burning efficiency and reducing attrition aspect.

Description

technical field [0001] The invention relates to a feeding device, in particular to a non-mechanical feeding method for fine fuel accumulation and combustion enhancement. Background technique [0002] Light and floating biomass or fine powder fuel refers to rice straw, wheat straw, corn stalks, etc., rice husk, bagasse, furfural slag, etc. Low volatile coal with a diameter of less than 1mm) and a content of more than 30%. Their common feature is that they are blown out of the furnace before they are completely burned after entering the furnace, which greatly affects the primary burnout rate of the fuel. What is more serious is that the frivolous or fine powder fuel entering the heating surface of the tail often causes Secondary combustion or even deflagration can cause severe damage to boilers and related auxiliary equipment and even cause fatal accidents. At the same time, the easy bridging of straw and other biofuels and the easy tempering at the feeding port often lead t...
