Briquette formula with high calorific value

Abstract

The invention discloses a briquette formula with high calorific value. The formula comprises coal and water glass. The concentration of the water glass additive is set to be 3.2 moduli. The water glass is 10-30% of the briquette by weight and the coal is 70-90% of the briquette by weight. If the concentration of the water glass additive is less than 3.2 moduli, the proportion is correspondingly increased.

Description

Technical field: [0001] The invention relates to a briquette formula with high calorific value technical background: [0002] In the 1980s, honeycomb coal began to be promoted in China. At that time, the cost of coal was low, tens of yuan per ton. Honeycomb coal is formed by adding yellow mud adhesive to coal, and it has not changed until now. However, today, the price of coal has risen dozens of times, cities are expanding, arable land is decreasing, and urban waste is increasing. If the adhesive of honeycomb coal is still yellow mud, although its cost is low, the yellow mud has poor viscosity. 5500 kcal / kg anthracite has an ash content of about 30%. One ton of 5500 kcal / kg anthracite will add 300 kg For the above yellow mud, the ash content increases to 52%, and its calorific value drops below 3500 kcal / kg. Because the calorific value drops, the firepower is small during combustion, and the combustion is incomplete, the thermal efficiency drops significantly, and the dr...

If the adhesive of honeycomb coal is still yellow mud, although its cost is low, the yellow mud has poor viscosity. 5500 kcal / kg anthracite has an ash content of about 30%. One ton of 5500 kcal / kg anthracite will add 300 kg For the above yellow mud, the ash content increases to 52%, and its calorific value drops below 3500 kcal / kg

Due to the decrease of calorific value, low firepower during combustion, and incomplete combustion, the thermal efficiency drops significantly, with a drop rate of more than 30%.

At the same time, a large amount of urban waste has been increased, increasing the amount of waste disposal

Third, the cinder separation work is added for the energy conversion of municipal solid waste, which makes the progress of energy conversion more difficult
