Petroleum coke powder full oxygen combustor

Abstract

The invention relates to a petroleum coke powder full oxygen combustor. The petroleum coke powder full oxygen combustor comprises an outer pipe, a combustor support used for sleeving the outer pipe, an inner pipe sleeved in the outer pipe, a coke powder gun which is sleeved in the inner pipe and stretches into a combustion kiln, as well as a Venturi pipe arranged on the head ends of the inner pipe and the outer pipe, wherein the Venturi pipe comprises a venturi inner pipe arranged on the head of the inner pipe and a venturi outer pipe arranged on the inner wall of the outer pipe; the inner wall of the outer pipe and the outer wall of the inner pipe form an oxygen gas channel in a surrounding manner, and the tail end of the oxygen gas channel is connected with outside oxygen equipment through an oxygen gas interface arranged on the outer pipe; the head end of the oxygen gas channel forms a jet orifice through a venturi channel of the venturi pipe; and the tail end of the coke powder gun is connected with an outside coke powder supplying device and is provided with an atomizer, and a gun nozzle at the head end of the coke powder gun extends out from the jet orifice to be inserted into the combustion kiln. The petroleum coke powder full oxygen combustor provided by the invention has the advantages of reasonable structure, energy conservation and environmental protection, and can ensure coke powder to fully burn, and can greatly improve coke powder utilization ratio.

Description

【Technical field】 [0001] The invention relates to a kiln burner, in particular to a pure oxygen combustion-supporting burner using petroleum coke powder as fuel. 【Background technique】 [0002] The glass industry is a high-energy-consuming industry, and the fuel cost accounts for about 30-50% of the glass cost, and the glass melting furnace is the equipment that consumes the most energy in the glass production line. At present, the fuel used in the glass field is basically heavy fuel oil such as petroleum. We know that the energy of our earth is limited. With the development of the economy, the demand for energy will increase. On the other hand, people are concerned about environmental protection. Awareness is rising day by day, and the general practice of mankind is to hope for breakthroughs in renewable energy and to improve energy utilization. As the most important fuel for human beings, petroleum will produce various intermediate products in the refining process. It wou...

Problems solved by technology

At present, the petroleum coke powder kiln in the glass factory directly pumps air into the burner of the kiln, and uses the oxygen in it to support combustion. Difficult to fully mix with oxygen, which will cause insufficient combustion of coke powder, and unburned coke powder particles will be discharged into the atmosphere along with the exhaust gas, so the utilization rate of coke powder in the burner of the current kiln is not high, and it is not energy-saving Environmental friendly
