Embodiment Construction

[0074] Take the preparation of 800kg combustion accelerant as an example:

[0075] ①. Weighing: Weigh the raw material potassium chlorate KClO according to the formula ratio of different types of combustion accelerants 3 7.5kg, potassium chloride KCl 5kg, potassium dichromate K 2 Cr 2 o 7 11kg, potassium permanganate KMnO 4 2.5kg, potassium carbonate K 2 CO 3 5kg, cerium oxide CeO 1kg, aluminum oxide Al 2 o 3 1kg, sodium chloride NaCl 10kg, sodium carbonate Na 2 CO 3 7kg, put it into a special turnover container, and fill in the order of the production process feeding list.

[0076] ② Ball milling and sieving: according to the requirements of premixed particles, ball mill the raw materials through a 300-mesh sieve, re-mill the unqualified ones to meet the premixing requirements, put them into a special turnover container, and fill in the production process feed list to transfer.

[0077] ③. Premixing: The speed of the mixer is 30-50 rpm, the maximum input amoun...

Abstract

The invention relates to a coal combustion-supporting agent, in particular to an energy-saving coal combustion-supporting agent which is applicable to different types of coal-fired boilers and can inhibit the emissions of harmful substances of soot, sulfur dioxide and the like and a preparation method thereof. The combustion-supporting agent is prepared by five process steps of material weighing,ball-milling screening, pre-mixing, pre-dissolving and reaction packaging and by taking potassium chlorate, potassium chloride, potassium dichromate, potassium permanganate, potassium carbonate, cerium oxide and the like as raw materials, and the combustion-supporting agent is characterized by energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a coal combustion enhancer, in particular to an energy-saving coal combustion enhancer suitable for different types of coal-fired boilers and capable of suppressing the discharge of smoke, sulfur dioxide and other harmful substances and a preparation method thereof. Background technique [0002] In the 21st century, the pressure on global energy supply is becoming increasingly tense, and the situation of energy and environmental protection in my country is even less optimistic. Energy conservation and environmental protection has become the basic goal of the country's "Eleventh Five-Year Plan" economic and social development plan, and has become a huge strategic task for the country's future development. At present, most northern cities in my country still use traditional coal-fired boilers for industry and heating. Traditional coal-fired boilers have low thermal efficiency, high energy consumption, and serious air pollution. ...
