Abstract

The invention relates to a compound combustion beam for a lime kiln. The compound combustion beam consists of a beam body, nozzles and a T-shaped cover, wherein the nozzles are positioned on two sides and the lower part of the beam body; the beam body is provided with a cavity for heat-transfer oil to circulate; the cavity for the heat-transfer oil to circulate is connected with a heat-transfer oil inlet and a heat-transfer oil outlet; the beam body is separated into an upper part and a lower part by a clapboard; the upper part of the beam body comprises a gas channel, an upper combustion air channel and gas nozzles; the gas channel is connected with the gas nozzles; the gas nozzles are opposite to the nozzles on the two sides of the beam body; the lower part of the beam body is provided with a pulverized coal pipeline, pulverized coal nozzles and a lower combustion air channel; the pulverized coal pipeline are connected with the pulverized coal nozzles; and the pulverized coal nozzles are opposite to the nozzles on the lower part of the beam body. According to the compound combustion beam for the lime kiln, the beam body of the compound combustion beam is separated into two parts through the clapboard, upper gas or lower pulverized coal can be selected to be independently or simultaneously used, the operation flexibility of the combustion beam is improved and the usability of the combustion beam is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion equipment, and relates to a combustion beam for a lime kiln, in particular to a composite combustion beam using gas and solid fuels. Background technique [0002] Burning limestone in the beam kiln section is a new technology for lime production. The beam type lime kiln has the advantages of low energy consumption, good quality of lime products, strong production capacity, large operating flexibility, etc., and is widely used in lime production for metallurgy, chemical industry and other purposes. The combustion beam is the core equipment of the beam-type lime kiln. The beam body of the combustion beam is equipped with burners, fuel pipelines and combustion-supporting air pipelines. The fuel pipelines and combustion-supporting air pipelines deliver fuel and combustion-supporting air to the burners. to burn. The applicant's patent application number is 200320111077.3, and the utility model pat...
