Water coke slurry buring technology

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...

AI Technical Summary

Problems solved by technology

Since the water coke slurry is made of petroleum coke with low ash, low volatile matter, and high calorific value, and has about 30% water, it is first heated and evaporated after entering the furnace, and due to the influence of the latent heat of water vaporization, the water coke slurry catches fire It is more difficult to stabilize the combustion process. Because of this, water coke slurry has not been reported as a fuel for industrial kilns or boilers.
