Abstract

This invention relates to a formulation of chemical material, particularly combustion-aid agent for increasing combustion efficiency of boiler. It is composed of (by wt.%): a complex of sodium nitrate and potassium nitrate 10-20, carbonate(s) (including sodium carbonate, potassium nitrate or their mixture) 25-45%, industrial salt (including sodium chloride, potassium chloride or their mixture) 20-55, iron sesquioxide 1-5, the mixture of alumina, silicon oxide, calcium oxdie, magnesium oxide 5-20. This invention combustion-aid agent has advantages of: (1). full combustion, with increased coal combustion efficiency, and energy-saving, (2). sulfur-removal and scale-removal, by sintering sulfur scale, carbon monooxide and coal-dust together, (3). simple prodn. process, merely comprising drying, and pulverizing.

Description

The boiler auxiliary combustion agent

One, technical field: the invention discloses a kind of formulation of chemical material, particularly a kind of boiler auxiliary combustion agent that is used to improve boiler combustion efficiency.

Two, background technology: present boiler, often adopts and spray Organic Chemicals in boiler, as crude oil, lightweight oil or the like in the insufficient or burning difficulty in burning.This method has the effect of interim raising coal burning, but can not burn owing to containing a large amount of tar in the oil product, causes interior coking of boiler and knot charcoal more serious.

Three, summary of the invention: purpose of the present invention is exactly the problem that exists at aforesaid method, provides a kind of boiler auxiliary combustion agent of adopting the inorganic salt composition, with the carbon deposit in the thorough solution boiler combustion and the problem of coking.

Its technical scheme is to comprise the following raw materials by weight percent composition: saltpetre SODIUMNITRATE complex compound 10-20%, carbonate 25-45%, Industrial Salt 20-55%, ferric oxide 1-5%, aluminum oxide, silicon oxide, calcium oxide, magnesian mixture 5-20%.Carbonate wherein comprises yellow soda ash, salt of wormwood or its mixture, and Industrial Salt can be sodium-chlor, Repone K or its mixture.

Ignition dope of the present invention has: 1, burning is perfect, improves the efficiency of combustion of coal, save energy; 2, desulfurization, detergency, and obnoxious flavoures such as sulphur, dirt, carbon monoxide is fixed with coal ash, discharge reduce the exhaust gas discharging amount; 3, processing only needs dry, pulverizing, and safe and convenient to use, consumption is few, and cost is low.

Four, description of drawings: do not have

Five, specific embodiment:

Embodiment 1: take by weighing saltpetre SODIUMNITRATE complex compound 15% by weight percentage, yellow soda ash 35%, sodium-chlor 40%, ferric oxide 1.5%, aluminum oxide 2.5%, calcium oxide 2%, the mixture 5-20% of magnesium oxide 4%.To mix behind the raw material drying, be ground into powder, the ratio in 0.002% be mixed use with coal.

Embodiment 2: take by weighing saltpetre SODIUMNITRATE complex compound 12% by weight percentage, salt of wormwood 33%, Repone K 45%, ferric oxide 1.5%, silicon oxide 1%, aluminum oxide 2.5%, calcium oxide 2%, the mixture 5-20% of magnesium oxide 3%.To mix behind all raw material dryings, be ground into powder, the ratio in 0.002% be mixed use with coal.

Claims (2)
