A double-chamber kiln burning fuel with low calorific value

Abstract

The invention discloses a double-chamber kiln burning fuel with low calorific value, which includes a No. 1 kiln body and a No. 2 kiln body. The upper middle part of the No. 1 kiln body and the upper middle part of the No. 2 kiln body are jointly fixedly installed with a feeding device, and the upper right end of the No. 1 kiln body and the upper left end of the No. 1 kiln body are jointly fixedly connected with a preheating device. The lower part and the lower part of the left end of the No. 1 kiln body are jointly fixed with a cooling device. The double-chamber kiln for fuel with low calorific value described in the present invention can increase the combustion temperature of fuel with low calorific value through branch pipes, main pipes, combustion chambers and heat storage boxes, and optimize the calcination effect; and the cooling device can realize effective heat dissipation of materials Transformation and recycling further reduce energy consumption; the double-chamber kiln can realize the mutual switching between the two kiln bodies to complete the continuous production of materials; and the feeding device can make the double-chamber kiln unloading convenient and reduce the labor intensity of the staff.

Description

technical field [0001] The invention relates to the technical field of industrial kilns, in particular to a novel double-chamber kiln burning fuel with low calorific value. Background technique [0002] The process of calcining and decomposing limestone raw materials into lime products needs to go through the storage zone, preheating zone, calcination zone and cooling zone in the kiln. However, traditional industrial kilns are mostly single-chamber kilns, which often have the following problems during use: [0003] On the one hand, the double-chamber kilns currently on the market are all standard double-chamber kilns. This standard double-chamber kiln must use high-calorific-value fuels to meet the design specifications and produce qualified products. High-calorific-value fuels refer to fuels with a calorific value above 1600kcal. fuels, such as pulverized coal, natural gas, coke oven gas, mixed gas (>1600kcal), etc., but some companies do not have these types of fuels, ...

AI Technical Summary

Problems solved by technology

The use of low-calorific-value fuels restricts the application of double-chamber kilns

[0004] On the other hand, the existing single-chamber kiln cannot effectively convert and recover the heat in the material during the cooling process, making the energy utilization rate low and increasing the production cost; the existing single-chamber kiln often calcines The high-calorie flue gas generated in the process is directly discharged, and the single-chamber kiln cannot realize the continuous production of materials, which reduces the production efficiency; the existing single-chamber kiln or double-chamber kiln is often inconvenient in the process of calcination and blanking, resulting in The labor intensity of the staff increases, increasing their labor burden
