Abstract

A combustion technique for water-coke slurry features that a pre-combustion chamber with secondary tangential air inlet, a cyclone burner of primary air at one end of said pre-combustion chamber and a spray gun in the center of cyclone burner for atomizing the water-coke slurry are used. The outlet of said precombustion chamber is communicated to industrial furnace. The temp in the pre-combustion chamber is at least 950-1000 deg.C.

Description

Technical field

[0001] The invention belongs to the combustion technology of water coke slurry, and specifically refers to the pre-combustion of water coke slurry before entering the furnace of an industrial furnace or boiler. Background technique

[0002] Water coke slurry is a slurry fuel made of petroleum coke powder with a certain fineness and water with a small amount of additives. It can be stored and transported for a long time. From the perspective of energy utilization, petroleum coke meets the requirements of high calorific value and low ash content. Slurry requirements; therefore, as a new type of clean fuel that replaces oil or coal, water coke slurry has a wider application prospect. Since the water coke slurry is made of petroleum coke with low ash content, low volatile matter and high calorific value, it has about 30% water. After entering the furnace, it is first heated and evaporated, and due to the influence of the latent heat of water vaporization, the water co...
