Embodiment 1

[0027] The high-temperature-resistant honeycomb coal includes coal powder, clay and kaolin, the mass ratio of the coal powder and the clay is 100:30, and the mass content of the kaolin is 20-30% of the clay. The main mineral component in the kaolin is kaolinite, and its crystal chemical formula is 2SiO 2 .Al 2 O 3 .2H 2 O.

Embodiment 2

[0029] The high-temperature-resistant briquettes include coal powder, clay and kaolin, the mass ratio of the coal powder and the clay is 100:30, and the mass content of the kaolin is 30-40% of the clay. The main mineral component in the kaolin is kaolinite, and its crystal chemical formula is 2SiO 2 .Al 2 O 3 .2H 2 O.

Embodiment 3

[0031] The high-temperature-resistant briquettes include coal powder, clay and kaolin, the mass ratio of the coal powder and the clay is 100:32, and the mass content of the kaolin is 40-50% of the clay. The main mineral component in the kaolin is kaolinite, and its crystal chemical formula is 2SiO 2 .Al 2 O 3 .2H 2 O.

Abstract

The invention discloses high-temperature-resistant honeycomb briquette. The high-temperature-resistant honeycomb briquette is prepared from pulverized coal and sintering maintaining agents, the mass ratio of the pulverized coal to the sintering retaining agents is 100: 20-50, the sintering retaining agents are clay or kaolin containing aluminum oxide, and the sintering retaining agents are adjusted according to the content of aluminum oxide. The honeycomb briquette can have good shrinkage retainability and does not melt due to high temperature in the heating and calcining process, and calcined product pollution or furnace smelting due to fusion of honeycomb briquette in the calcining process can be avoided.

Description

Technical field [0001] The invention relates to the technical field of fuels, in particular to a high-temperature-resistant briquettes. Background technique [0002] Briquette is a low-cost fuel, using bituminous coal and anthracite as the main raw material. Honeycomb briquettes have a wide range of raw materials, low cost, convenient use, simple production, and can achieve the purposes of saving materials, time, and resources. Traditional honeycomb briquettes are made by mixing raw coal and clay with water. Clay mainly plays a role in shaping. The ratio of raw coal to clay is usually about 100:20-50. When calcining talc or kaolin, it is generally pressed into bricks and used in a wheel kiln. Or firing in a tunnel kiln, briquettes can be used as fuel. reference figure 1 , Put the bricks 1 and honeycomb coal 2 layers in the kiln for firing. As the calcining temperature of the fired products is as high as 1100-1400℃, in the high-temperature firing process, ordinary clay (usually ...
