Embodiment 1

[0024] With the bituminous coal gangue=95 after coal washing (in % weight), straw plant activated carbon=5 is mixed and made into comprehensive coal, and its calorific value reaches 8.92×10 6 J / kg, the volatile fraction is 11.24%, and the total sulfur is 2.13%. The volume of the clay brick fired with this comprehensive coal reaches 1200ml, and the compressive strength of the brick is 12.5MPa.

Embodiment 2

[0026] With (weight %) natural coal gangue=85, the plant activated carbon=15 of sawdust, mix and make comprehensive coal, its calorific value reaches 9.53 * 10 6 J / kg, the volatile fraction is 13.0%, and the total sulfur is 2.19%. The volume of the clay brick fired with this comprehensive coal is 1575ml, and the compressive strength of the brick is 12.6MPa.

Embodiment 3

[0028] With (calculation % weight) natural coal gangue=55%, cereal distiller's residue plant activated carbon=45% is mixed and made comprehensive coal, and its calorific value reaches 12.90 * 10 6 J / kg, volatile matter is 16.15%, and total sulfur is 1.29%. The volume of the clay brick fired with this comprehensive coal is 2875ml, and the compressive strength of the brick is 14.2MPa.

Abstract

The invention discloses a new burning-block and furnace fuel and preparing method, which is composed of 0-98 percent natural fuel waste or anthracite coal waste, 2-100 percent plant active carbon of straw or wood dust or chaff or wood and bamboo corner excess stock or secondary forest or cereal wine waste or traditional Chinese medicine waste, wherein the coal waste is dried into 0-3 mm grain grade to mix with plant active carbon, which is sintered into clay block with 11.0-13.4 Mpa anti-pressure strength and 160-190 KN breaking load.

Description

technical field [0001] The invention relates to a novel fuel for burning clay bricks or directly used in boilers and a preparation method thereof. Background technique [0002] At present, in coal mining in my country, the coal gangue in the mining process is discarded as waste out of its interests, and it has not been fully utilized. It not only occupies the land, but also pollutes the environment. This is a problem that has not been well resolved for a long time . , [0003] In addition, in people's daily life, common things such as straw, sawdust, leftovers from wood or bamboo processing industries, rice husks, grain dregs from wineries, and traditional Chinese medicine dregs from pharmaceutical factories, etc., although some people want to These "waste" are utilized, but due to the limitation of conditions, most of them are still discarded as waste, and they are not effectively utilized, especially they are used as fuel for burning clay bricks or directly as boiler fuel...
