Combustion supplementing type waste heat boiler

Abstract

The invention provides a combustion supplementing type waste heat boiler. The combustion supplementing type waste heat boiler can solve the problem that no high-temperature smoke is supplied to upstream equipment of an existing waste heat boiler or high-temperature smoke supply to the upstream equipment of the existing waste heat boiler is not stable, and consequently the heat supply requirement cannot be met. The combustion supplementing type waste heat boiler comprises a boiler barrel and a waste heat boiler flue. The waste heat boiler flue is horizontally arranged. A smoke inlet is formed in one end of the waste heat boiler flue, and a smoke outlet is formed in the other end of the waste heat boiler flue. The smoke inlet is connected with a high-temperature smoke discharge port of the upstream equipment. A heated face assembly is arranged in the waste heat boiler flue in the direction from the smoke inlet to the smoke outlet. The boiler barrel is connected with the heated face assembly through a circulation pipeline. The combustion supplementing type waste heat boiler is characterized by further comprising a combustion supplementing chamber composed of a film type water cooling wall, and the combustion supplementing chamber is provided with a combustion supplementing combustor; and the smoke outlet end of the combustion supplementing chamber communicates with the waste heat boiler flue through an adapter flue, the end, connected with the waste heat boiler flue, of the adapter flue is provided with a first flue gate valve plate, and a second flue gate valve plate is arranged at the smoke inlet position of the waste heat boiler flue.

Description

technical field [0001] The invention relates to the technical field of waste heat boilers, in particular to a supplementary combustion waste heat boiler. Background technique [0002] With the acceleration of industrialization and urbanization in our country, the government has formulated a strategic decision to build a resource-saving and environment-friendly society. Energy conservation, emission reduction, and comprehensive utilization of resources have become the goals of joint efforts of governments at all levels and enterprises. More and more enterprises have joined this industry, and the gradually mature waste heat recovery technology has also provided ideas for solving waste heat utilization. [0003] Waste heat boiler is a device that uses high-temperature flue gas generated by upstream equipment to exchange heat with working fluid to produce steam or hot water. However, at present, most projects do not generate high-temperature flue gas at the beginning of constru...

AI Technical Summary

Problems solved by technology

[0004] In view of the above problems, the present invention provides a post-combustion waste heat boiler, which can solve the problem that the existing waste heat boiler cannot meet the heat supply requirements due to the lack of high-temperature flue gas supply or the unstable supply of high-temperature flue gas in the upstream equipment.
