Type A flame path beam for multi-fuel lime shaft kiln

Abstract

The invention relates to a type A flame path beam for a multi-fuel lime shaft kiln. The type A flame path beam comprises a beam body, a heat-conducting oil inlet, a heat-conducting oil outlet, blocking plates, a primary heat-conducting oil cooling channel and a secondary beam cooling channel, wherein the beam body is divided into an inner layer and an outer layer; space between the inner layer and the outer layer is divided into a plurality of heat-conducting oil channels by the blocking plates; holes are reserved among the blocking plates between every two adjacent channels so as to allow the heat-conducting oil to flow from one heat-conducting oil channel into an adjacent heat-conducting oil channel; a semi-closed space in the lower part of the beam body is a flame channel space and is used for containing flames formed by combusting fuels by a burner and the produced high-temperature flue gas; a secondary cooling space is formed in the upper part of the beam body and can be used for performing secondary cooling on the flame path beam by using natural wind or other media. In order to reduce material resistance, the beam body is designed into a type A structure, and then the weight of the beam is reduced.

Description

【Technical field】 [0001] The invention relates to a lime shaft kiln, in particular to a fire channel beam for a multi-fuel lime shaft kiln, which belongs to the technical field of calcining equipment. 【Background technique】 [0002] Iron and steel industry, calcium carbide industry, alumina industry, refractory materials and other industries are all major lime consumers. With the rapid development of these industries, the important industrial raw material they need - lime has not increased accordingly, which has caused the tension of lime, which has stimulated the launch of a large number of social lime kilns, and the blooming of earth-fired kilns everywhere. caused serious pollution to the environment. Under such circumstances, the national and local governments have successively issued a series of policies and regulations to regulate earth-fired kilns, but it is difficult to achieve the expected results because of the stimulation of demand. Therefore, in order to control...

Problems solved by technology

[0007] In order to solve the above problems, the object of the present invention is to provide a kind of A-type fire beam for multi-fuel lime shaft kiln which can make lime shaft kiln calcining efficiency high, calcining evenly, and can effectively improve the daily output of single kiln, to solve the problem of existing lime When the kiln uses high calorific value fuel (coke oven gas, natural gas, coal powder, etc.) to calcinate lime, the fuel efficiency is low, the calcining effect is poor, and the daily output is low
