Novel combustion-supporting ignition system

Abstract

The invention relates to a novel combustion-supporting ignition system. In the combustion-supporting ignition system, an air compressor, an air storage tank and an airflow stop valve are connected by pipelines sequentially and then are connected with an air inlet of a fuel oil gun; an oil storage tank, an oil pump, an oil filter, an atomizing chamber and an oil flow stop valve are connected by pipelines sequentially and then are connected with an oil inlet of the fuel oil gun; the transmitting end of an ultrasonic transducer and the atomizing chamber are fixed together; a primary combustion chamber is fixedly arranged at the middle position of a right opening of a material pipe; a protective pipe is communicated with the inside of the primary combustion chamber from the outside of the material pipe; the fuel oil gun is inserted into the primary combustion chamber from the protective pipe; a secondary combustion chamber is fixedly arranged at a right end opening of the material pipe, and is in unenclosed opening connection with the material pipe; a secondary air inlet shield is arranged at the right end of the material pipe coaxially, and the secondary combustion chamber is covered by the lining of the secondary air inlet shield; and a secondary air inlet pipe is communicated with the inside of the secondary air inlet shield.

Description

technical field [0001] The invention relates to a combustion-supporting ignition system, in particular to a novel combustion-supporting ignition system, which belongs to the technical field of combustion-supporting accessories. Background technique [0002] At present, in coal-fired power plants, boilers and combustion equipment are generally realized by spraying heavy oil into the furnace through special accessories when they start to operate or change from extremely low load to high load operation. It has the advantages of simple equipment and convenient use, but the amount of heavy oil required is large and the combustion of heavy oil is insufficient, so the operating cost is relatively high. The environment also has a serious impact, and in addition, this mode of operation also has the disadvantage of slow response speed. Contents of the invention [0003] The purpose of the present invention is to provide a novel combustion-supporting ignition system. This combustion...
