Rare earth high-heat ignition moulded coal

Abstract

The present invention relates to a rare earth high thermal energy ignition briquette, belonging to the fuel field. The coal is characterized in that the compositions in percentage by weight of the briquette are: 42 to 62 percent of coal, 18 percent of organic cementation agent, 5 percent of sodium chlorate, 15 percent of ammonium nitrate, and 0.5 to 20 percent of rare earth metal additive. Compared with the prior briquette, the compound high thermal energy ignition briquette is improved by 50 to 70 percent in thermal efficiency and heat quantity, at the same time, since the briquette is easy in ignition, quick in firing, rational in structure, and moisture-proof, the problem of generation of coal dry firing toxic gases is completely solved, the discharge of dusty gases is reduced, and the discharge of ashes is substantially solved. At the same time, the desulphurization rate can reaches 48 to 51 percent and the discharge amount of SO2 decreases by 47 to 65 percent compared with that of the prior briquette. For example, in a stress test where a profile size is [phi] 50 mm multiply 60 mm, the cold strength of the briquette exceeds 100 N / piece, and the calorific intensity is between 120 and 130 N / piece.

Description

1. Technical field: [0001] The invention relates to a rare earth high heat energy ignition briquette, which belongs to the field of fuel. 2. Background technology: [0002] Most of the commercially available briquettes are composed of pulverized coal with some sulfur or phosphorus and clay added. These briquettes all have several major defects such as difficult ignition, tidal resistance, and low calorific value. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a kind of rare earth that is easy to ignite, fire quickly, moisture-proof, high in heat, less polluting gas and dust emission, environmentally friendly and energy-saving, high in coal utilization rate, and widen the use range of lanthanum and cerium metal in rare earth resources High heat energy ignition briquette. [0004] Technical solution: the present invention comprises following material composition by weight percentage: [0005] 42% to 62% of coal, 18% of organic bin...
