Civil briquette starch plasticizer and its preparing process

Abstract

The invention pertains to a fuel, in particular relates to a forming agent of an environment-friendly high-heat coal for civil use and a preparation method thereof. The preparation method of starch forming agent of the civil use coal is as follows: a. the prescription of the forming agent according to weight proportion is as follows: 2.4-7 percent of starch, 93-97.6 percent of water, 14-33 percent of caustic soda water NaOH, 67-86 percent of water, b. the preparation method is as follows: the 2.4-7 percent of starch and the 93-97.6 percent of water are mixed together and stirred evenly, then is added with the 14-33 percent of caustic soda water NaOH and the 67-86 percent of water and stirred evenly to become a pasty matter that is the coal forming agent. The starch used for making the forming agent can be wheat starch, potato starch, broomcorn starch, corn starch. The forming agent of civil use coal is added into coals of different properties as cohesive forming agent according to a ratio of 10 percent-30 percent. Therefore, since being added with a small amount of the forming agent containing combustible starch, the coal has the advantages of burning completely, strong firepower, high heat generating value, no furnace ash and slag produced, little environment pollution, light and easy to convey and low cost.

Description

technical field [0001] The invention belongs to fuel, and in particular relates to a civil environment-friendly high-heat briquette forming agent and a preparation method thereof. Background technique [0002] At present, the general civilian briquette production generally adopts coal products in the market, and uses red clay, loess, white clay, and coal gangue as product molding agents. Due to the addition of soil and non-combustible substances in its products, the product itself has the following shortcomings, such as incomplete combustion, weak firepower, and low calorific value, resulting in a large amount of ash and slag, causing environmental pollution. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned civil briquettes that exist in the prior art because soil non-combustible substances are added into their products, resulting in incomplete combustion, weak firepower, and low calorific value, resulting in a large a...
