A high-pressure internal mixing atomization injection vegetable oil or bio-oil combustion system and method for an industrial furnace

Abstract

The invention provides an industrial furnace high-pressure inner-mixed type system for atomizing vegetable fat or bio-oil to be burned and a method thereof, and belongs to the technical field of energy sources and environments. The vegetable fat or the bio-oil which is filtered and dehydrated serves as an incendiary agent, the high-temperature air serves as an atomizing medium, the oil gas is conveyed into a high-pressure oil and gas mixing chamber of a burner through an automatic adjusting valve control device, a high-pressure blowing nozzle is inserted into a furnace combustion chamber from the periphery of an industrial furnace, the nozzle atomizes the oil gas into the combustion chamber of the industrial furnace to be burned in a corner tangential mode, hot air fed from other inlets supply sufficient oxygen, the problems that the vegetable fat and the bio-oil atomizing particles are large, incomplete in combustion, low in combustion efficiency and the like are solved, and the system has the advantages that the vegetable fat and the bio-oil atomizing particles are small, the atomizing quality is good, combustion is sufficient, the combustion efficiency is high, oil is saved, and low emission is achieved.

Description

technical field [0001] The invention relates to a high-viscosity vegetable oil or bio-oil atomization injection technology and biomass energy conversion and utilization technology, in particular to an industrial kiln high-pressure internal mixing type atomization injection vegetable oil or bio-oil combustion system and its The method belongs to the technical field of energy and environment. Background technique [0002] With the rapid development of industry, the demand for fuel is increasing. In the production process of various industrial furnaces, energy saving, reducing operating costs, reducing environmental pollution and other issues have become enterprises' survival in market competition. The key issues that must be faced and resolved in order to achieve peace and development. In the combustion system of industrial furnaces, most of the fuels currently used are coal, petroleum fossil fuels, and industrial gas. And environmental pollution, and higher energy consumpti...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an industrial kiln high-pressure internal mixing atomization injection vegetable oil or bio-oil combustion system and its method, using filtered and dehydrated vegetable oil or bio-oil as a combustion agent, and using high-temperature The air is used as the atomizing medium, and the oil and gas are sent into the high-pressure oil-gas mixing chamber of the burner through the automatic adjustment valve control device. The high-pressure injection oil gun is inserted into the combustion chamber of the furnace from the surroundings of the industrial furnace, and the nozzle is atomized in a way of cutting circles at four corners. It is injected into the combustion chamber of the industrial kiln for combustion, and the hot air sent from other inlets provides sufficient oxygen to solve the problems of large atomized particles of vegetable oil and bio-oil, incomplete combustion, and low combustion efficiency.
