High-mixing-ratio ignition tank

Abstract

The invention discloses a high-mixing-ratio ignition tank, and belongs to the technical field of boiler soot blowing. The ignition tank comprises an air inlet connecting pipe, a gas chamber, a mixing chamber, an ignition chamber and a flame outlet pipe, wherein the gas chamber, the mixing chamber and the ignition chamber are arranged in the ignition tank in sequence according to a gas inlet direction; the air inlet connecting pipe is communicated with the gas chamber and the mixing chamber; a secondary mixed gas shunt plate is arranged between the mixing chamber and the ignition chamber; a gas mixing inclined hole is formed in the middle part of the air inlet connecting pipe; primary mixed gas outlet inclined holes are formed in the tail part of the air inlet connecting pipe; a plurality of vertical first through holes and inclined second through holes are uniformly formed in the secondary mixed gas shunt plate; the flame outlet pipe is communicated with the ignition chamber. According to the high-mixing-ratio ignition tank, mixed gas can uniformly enter the ignition chamber by improving the structure of the air inlet connecting pipe and arranging the shunt plate between the mixing chamber and the ignition chamber, so that the mixing full degree of air and gas is greatly improved.

Description

technical field [0001] The invention relates to the technical field of boiler soot blowing, in particular to an ignition tank with a high mixing ratio. Background technique [0002] The soot blower is an indispensable and important auxiliary equipment for various waste heat boilers and utility boilers. It plays a vital role in improving the heat exchange efficiency of each heating surface of the boiler, that is, increasing the output of the boiler. The hybrid ignition tank is one of the most important components on the shock wave generation system. Gas and air are mixed in the ignition tank, and then transported to the shock wave generator tank through the outlet pipeline. The uniformity of gas mixing in the ignition tank directly affects the soot blowing effect. The existing hybrid ignition tank only realizes simple mixing through gas and air direct flow and confluence when gas and air are mixed, which leads to insufficient mixing of gas and air, which directly affects the...
