Multipurpose direct flow pipe shielded heat carrier boiler

Abstract

The multipurpose direct flow pipe plate type heat carrier boiler can realize the turbulent flow, circulation and flow speed control of heat carrier, the lateral flushing to heat releasing pipes and other uses, and has obviously increased heat transfer coefficient and heat transfer area, greatly improved heat transfer condition, effective prevention of overheat and cracking of heat carrier, carbon deposit, coking and electric heating element damage, and convenient boiler cleaning and maintenance. The heat carrier boiler has cylindrical kettle, and spiral flow channels comprising pipe plate barrel, partition boards, pipe plate and cylinder, with the flow channels being connected serially or in parallel. The heat carrier is forced to flow inside the flow channels for heat exchange. The heat carrier boiler can bear pressure and may be vertical or horizontal, and the technology of the present invention is especially suitable for indirect resistive boiler with organic heat carrier, direct flow hot water boiler, etc.

Description

technical field [0001] The invention belongs to a boiler device for heat energy conversion, in particular to a heat carrier boiler capable of realizing forced direct current flow and lateral flushing of heating pipes. Background technique [0002] At present, the known resistance type organic heat carrier boiler adopts a shell type body structure, which is a volume type boiler. In this structure, the flow of the organic heat carrier in the body is basically a natural circulation, the flow rate is extremely low, and effective circulation cannot be obtained. The cooling capacity of (heat transfer oil) is much lower than that of water, so it is easy to cause overheating and cracking of the heat carrier, as well as carbon deposition and coking on the outer wall of the heating tube. As a result, the heat transfer oil is deteriorated and scrapped, and the electric heating element cannot be cooled due to the load overload and fuse. In severe cases, the casing will burst and cause ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the existing shell-type organic heat carrier boilers, the flow rate of the organic heat carrier is too low, the heating tube cannot be cooled reliably, and the heat carrier is easy to deposit carbon and coke, the present invention provides a direct-flow tube-panel heat carrier boiler
