Fire coal additive

Abstract

The invention discloses a fire coal additive, which comprises the following steps: allocating 150-170 Kg potassium perchlorate and 100-120 Kg as firing agent; allocating 80-100 Kg natrium hydroxydatum, 200-220 Kg soda and 150-180 kg barium nitrate as activator; allocating 80-100 Kg salt and 80-100 Kg potassium chloride as findings; fetching each material; disintegrating with grinder; sieving; mixing completely; getting the product; using mutual action of silicon trioxide, di-iron trioxide, alumind, titania, calcium oxide, magnesium oxide and metal alkalinous material; increasing the temperature of back furnace tank; decreasing the carbon content of cinder; improving calorific efficiency of boiler; making rate of economizing coal reach above 16% and carbon content low above 20%. So it can decrease the discharge of black smoke, which belongs to environment-friendly type energy efficient technology.

Description

technical field [0001] The invention belongs to a special energy-saving additive for burning coal, in particular to a coal-burning additive suitable for boilers burning various shaped coals. Background technique [0002] At present, most of the popular coal-fired energy-saving agents on the market use solid oxidant technologies such as potassium permanganate and sodium nitrate, and rely on coal combustion oxidants to generate oxygen in the boiler to achieve the purpose of combustion-supporting and coal-saving. Production practice has proved that this method alone The oxidant produces oxygen in the boiler to save coal, but the effect is very insignificant. The reason is that oxygen only plays a combustion-supporting role in coal combustion, helping coal to burn without generating calorific value, and the addition of oxidant per ton of coal is limited. , the oxygen produced is also very limited, especially in the actual operation of the boiler, various types of boilers are gen...

[0002] At present, most of the popular coal-fired energy-saving agents on the market use solid oxidant technologies such as potassium permanganate and sodium nitrate, and rely on coal combustion oxidants to generate oxygen in the boiler to achieve the purpose of combustion-supporting and coal-saving. Production practice has proved that this method alone The oxidant produces oxygen in the boiler to save coal, but the effect is very insignificant. The reason is that oxygen only plays a combustion-supporting role in coal combustion, helping coal to burn without generating calorific value, and the addition of oxidant per ton of coal is limited. , the oxygen produced is also very limited, especially in the actual operation of the boiler, various types of boilers are generally equipped with different types of blowers, and there is no shortage of oxygen. It can be seen that relying on oxygen for combustion does not bring better savings coal effect

In addition, some oxidants such as potassium nitrate will produce harmful substances such as sodium nitrite after burning, and these harmful substances will be discharged into the atmosphere along the flue, which is not conducive to environmental protection
