[0046] Measurement methods

[0047] 1. Measurement method of briquette drop strength

[0048] According to the method stipulated in MT / T925-2004, the main points of the measurement method are: take a certain amount of briquette samples and weigh them, drop them freely from a height of 2m onto a steel plate with a specified thickness, and drop the briquettes with a particle size greater than 13mm from the dropped briquettes. The briquettes were dropped again for a total of 3 times, and the drop strength of the briquettes was represented by the percentage of the mass of the briquettes with a particle size greater than 13 mm after the third drop to the mass of the prototype coal sample.

[0049] 2. Measurement method of thermal stability of briquette

[0050] According to the industry standard MT / T924-2004, the main points of the measurement method are: select a crack-free and basically complete molded coal from the molded coal samples taken according to the regulations of...

Abstract

The invention relates to a binder for pressure gasification briquettes, in particular to a pressurized fixed bed gas making briquette binder comprising silica gel, siallitic soil, ammonium carbamate and an auxiliary binder. The invention also relates to the briquettes comprising the briquette binder and a preparation method thereof.

Description

technical field [0001] The present invention relates to a kind of pressurized fixed-bed gas-making briquette binder, more particularly to a kind of pressurized fixed-bed gas-making briquette binder comprising silica gel, silica-alumina and ammonium carbamate and auxiliary binder : The present invention also relates to a briquette comprising the briquette binder and a method for preparing the briquette. Background technique [0002] At present, my country's normal-pressure fixed-bed gas-making briquette technology is relatively mature. The country uses about 10 million tons of gas-making briquettes every year. With the development of gasification technology and gasification scale, the use of large pressurized gasifier is a development direction. Relying on its unique advantages, Lurgi pressurized gasifier has been promoted and applied in more and more enterprises. There are about 200 Lurgi furnaces in operation in my country, all of which use lump coal as raw material. In...
