Environment-protecting synergistic agent for fuel coal

Abstract

The invention discloses a bunker coal environment-friendly synergist, which comprises the following components by weight percent: 1 to 10 percent of ammonium bicarbonate, 1 to 8 percent of sodium bicarbonate, 1 to 10 percent of sodium carbonate, 1 to 5 percent of sodium nitrate, 1 to 10 percent of potassium nitrate, 1 to 15 percent of calcium carbonate, 1 to 10 percent of sodium hydroxide, 2 to 10 percent of calcium hydroxide, 1 to 10 percent of potassium permanganate, 3 to 15 percent of potassium chloride, 10 to 35 percent of sodium chloride, 1 to 10 percent of ammonium chloride, 1 to 15 percent of calcium chloride, 1 to 10 percent of borax, 1 to 10 percent of macaroni, 1 to 5 percent of potassium carbonate, 1 to 5 percent of calcium nitrate, 1 to 5 percent of iron oxide, and the balance being micro turpentine, sulfur and paraffin wax. The bunker coal environment-friendly synergist makes flame of combustion be more rampant and denser, the furnace temperature rise to a higher level, the hearth be brighter and cleaner and tail gas be cleaner.

Description

technical field [0001] The invention relates to a coal-burning additive, in particular to an additive for coal-fired environmental protection and efficiency enhancement. Background technique [0002] Coal used in boilers generally has problems of incomplete combustion and large loss of heat energy. The first reason is that carbon is not completely combusted, and there are two processes for carbon to burn when oxygen is sufficient: 2C+O 2 =2CO, 2CO+O 2 =2CO 2 The heat energy released in the first stage is about 28%, and the heat energy released in the second stage is about 72%. There are three processes in the combustion of carbon when oxygen is insufficient: 2C+O 2 =2CO, 2CO+O 2 =2CO 2 , C+CO 2 =2CO(C+CO 2 = 2CO is endothermic). In order to reduce the loss of heat energy during the combustion process of the boiler, it is generally not used to increase the gas flow to burn coal. When there is no supplement of other oxidants, energy waste and CO pollution will be caus...

AI Technical Summary

Problems solved by technology

Coking often occurs in coal combustion, which reduces the effective combustion rate of coal

The third is that the quality of the flame is low, the contact between the furnace and the outer flame is not close enough, the flame is not high enough, dense enough, and hot enough

The generation and increase of boiler scale directly reduces the heat absorption capacity of the boiler
