Abstract

The invention discloses a tunnel kiln radiation heat exchange type waste heat boiler. The tunnel kiln radiation heat exchange type waste heat boiler comprises a boiler steel structure supporting platform, a deaerator, a continuous pollution discharge expanding container, a regular pollution discharge expanding container, a water supply pump, a coal economizer water inlet collecting box, a coal economizer, a boiler barrel, a first-stage evaporator, a second-stage evaporator, a third-stage evaporator, a fourth-stage evaporator, a saturated steam collecting box, a low-temperature superheater, a desuperheater, a high-temperature superheater, a superheated steam outlet collecting box, a superheated steam outlet pipe and a water supply heater. The tunnel kiln radiation heat exchange type waste heat boiler solves the problems of long cooling time, high cost and low utilization efficiency of waste heat released in the process of cooling a product of a tunnel kiln, better improves the use effect of the product and promotes the progress and development of the industry.

Description

technical field [0001] The invention belongs to the field of waste heat reuse, and specifically refers to a tunnel kiln radiation heat exchange waste heat boiler. Background technique [0002] The tunnel kiln is a high-efficiency roasting kiln that is mainly promoted in my country's brick and ceramic industry. The cooling zone of the tunnel kiln has a large amount of high-temperature waste heat of about 1000 °C. The waste heat of tunnel kilns in brick and ceramic enterprises is mainly used to dry bricks or heat water for bathing and heating in winter. This part of waste heat only accounts for a small part of the waste heat of tunnel kilns, and a large amount of waste heat is discharged to the atmosphere, causing waste heat to the atmosphere. pollute. It takes a long time in the cooling process of the product produced in the tunnel kiln, which results in a long production cycle and low production efficiency, which increases the production cost. [0003] In order to overcome...
