High thermal efficiency regenerative heating furnace

Abstract

The invention discloses a high thermal efficiency regenerative heating furnace which is used for solving the problem that an existing regenerative heating furnace is low in thermal efficiency. The high thermal efficiency regenerative heating furnace comprises a furnace body, a partition wall divides an inner cavity of the furnace body into a combustion chamber and regenerative chambers arranged at two sides of the combustion chamber, the partition wall is provided with at least one combustion channel used for communicating the regenerative chambers with the combustion chamber. A heat accumulator is arranged inside each regenerative chamber, and is connected with a fuel combustion assisting pipeline and a fuel pipeline, and the fuel combustion assisting pipeline and the fuel pipeline are respectively connected with a combustion assisting gas source and a fuel source. The heat accumulator is further connected with a check valve capable of enabling fuel combustion assisting gas to enter the furnace body. The fuel pipeline is provided with a check valve capable of enabling the fuel to enter the furnace body. The high thermal efficiency regenerative heating furnace is capable of preventing burning smoke from entering the fuel combustion assisting pipeline and the fuel pipeline, and therefore ratio of the fuel and the fuel assisting gas is effectively controlled, and combustion efficiency is improved.

Description

technical field [0001] The invention relates to an industrial heating furnace, in particular to a regenerative heating furnace with high thermal efficiency. Background technique [0002] The regenerative heating furnace is a combination of a high-efficiency regenerative heat exchanger and a conventional heating furnace. It is mainly composed of a heating furnace body, a regenerator, and an air supply and smoke exhaust system. The regenerator is the main body of waste heat recovery from the flue gas of the regenerative heating furnace, and it is a part of the flue gas and air flow channel. In the heating furnace, the regenerators always appear in pairs, and one furnace can use one pair, or several pairs, or even dozens of pairs. The advantage of waste heat recovery in the regenerator is to make the furnace temperature more uniform. Due to the uniform distribution of the furnace temperature, the heating quality is greatly improved, and the product qualification rate is greatl...
