Chromium-based coke removal and ash removal coal saving agent composition for boiler and preparation method for composition

Abstract

The invention relates to coal burning additives used in coal burning boilers in the industries of power generation, thermoelectricity, petroleum, chemical engineering, metallurgy and the like, in particular to chromium-based coke removal and ash removal coal saving agent composition for a boiler. The composition is prepared from the following raw materials in parts by weight: 60-75 parts of chromic oxide, 10-16 parts of copper sulfate, 7-12 parts of cerium oxide, 10-15 parts of barium molybdate, 6-12 parts of manganese dioxide, 12-17 parts of potassium permanganate, 5-11 parts of potassium chlorate, 15-22 parts of zinc oxide, 8-13 parts of cobalt sulfate, 22-30 parts of potassium carbonate, 30-40 parts of active attapulgite clay and 0.1-0.3 parts of a penetrating agent JFC. The composition is added into the coal burning boiler, so that the coal saving rate is 8-25%, a furnace coking phenomenon is radically changed, the combustion time of fire coal can be prolonged, the heat efficiency of the boiler is improved, furnace tailings are reduced, the service life and repair cycle of equipment are prolonged, the emission of toxic and harmful gas and substances is reduced, and environmental protection effects of alleviating pollution and reducing emission are fundamentally achieved.

Description

technical field [0001] The invention relates to a coal-fired additive suitable for coal-fired boilers in industries such as power generation, thermoelectricity, petroleum, chemical industry, and metallurgy; specifically, it is a boiler chromium-based decoking, ash-removing, and coal-saving agent composition. The invention also relates to A preparation method of a boiler chromium-based coke-removing, ash-removing and coal-saving agent composition. Background technique [0002] my country is a big country that uses coal and is also rich in coal resources. However, the coal has high sulfur content, low calorific value, large ash content, and a large proportion of low-quality coal. Currently, chain furnace slag is commonly used as fuel again, and the slag with high carbon content has caused huge pollution to the environment. The coking and ash deposition in the boiler operation process is a major problem plaguing the boiler industry in my country, and it is also a worldwide pro...

Problems solved by technology

In order to remove the coking in the furnace, special equipment such as soot blowers are used to blow soot on a regular basis, which can remove the loosely deposited ash on the heating surface. High, with unlimited growth characteristics, difficult to remove by mechanical means

[0004] In recent years, in Hebei, Liaoning, Shaanxi and other regions, products similar to the present invention have been developed. They have been tested in coal-fired boilers. Although some have effects, the effect is not obvious, and some form glass bodies after being added to the furnace. Instead of coke, it makes the coke more firm
