Hot-blast stove secondary air inlet system

Abstract

The invention discloses a hot-blast stove secondary air inlet system which comprises a hot-blast stove body. A combustion cavity and an ash collecting cavity are formed in the hot-blast stove body, and a perforated plate is fixedly connected to the inner wall of the combustion cavity. A through hole is formed in the upper surface of the hot-blast stove body, and the inner wall of the through holeis provided with a sealing cover matched with the through hole in a sleeving manner. A fuel feeding port, a first air inlet and a second air inlet are formed in the side face of the hot-blast stove body, and a first air inlet pipe is fixedly connected to the inner wall of the first air inlet. By arranging the first air inlet pipe, normal combustion of fuel in the hot-blast stove body can be guaranteed. When the fuel amount needs to be increased, an adjusting shaft is rotated to enable an adjusting valve to control the air inlet amount of a second air inlet pipe, induced draft fan blades are pushed by airflow to rotate, and external air is guided to flow into the combustion cavity to achieve a combustion supporting effect. Thus, the whole system has the effect of enabling the fuel to be sufficiently combusted, and also can adjust heat generated by the fuel.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a secondary air inlet system for hot blast stoves. Background technique [0002] The hot blast stove is a thermal power machine, which was widely used in our country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. [0003] The existing hot blast stove has only one air inlet hole during combustion, so the size of the firepower cannot be adjusted, resulting in insufficient combustion of the material burned in the hot blast stove, which increases the consumption of energy. [0004] The invention provides a secondary air intake system for a hot blast stove. Contents of the invention [0005] The object of the present invention is to propose a secondary air intake system for a hot blast stove in order to solve the shortcomings in the prior art. [0006] In order to achieve the ab...
