Hot-blast stove with automatic heat supply temperature adjustment function

Abstract

The invention provides a hot-blast stove with an automatic heat supply temperature adjustment function. The hot-blast stove comprises a stove body and a combustion chamber installed in the stove body. A mixing chamber is further arranged inside the stove body. The mixing chamber is communicated with the combustion chamber. The mixing chamber is divided into a first mixing chamber body and a second mixing chamber body, wherein the first mixing chamber body and the second mixing chamber body are mutually communicated. The stove body is provided with a first opening and a second opening. Normal-temperature air is blown into the first mixing chamber body through the first opening. Cold air is blown into the second mixing chamber body through the second opening. The second mixing chamber body is communicated with an air outlet. According to the hot-blast stove with the automatic heat supply temperature adjustment function, the size of the combustion chamber is set more reasonably, so that the temperature of combustion is increased, and radiation intensity of combustion is enhanced; combustion is kept in the most reasonable working condition by adjusting the fuel quantity and air quantity inside the combustion chamber; the first mixing chamber body and the second mixing chamber body are arranged, the air inflow of the normal-temperature air of the first mixing chamber body is adjusted, and therefore process requirements of a heat-consuming device are better met.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a hot blast stove with automatic heating temperature adjustment. Background technique [0002] Existing hot blast stoves are divided into direct combustion type and indirect type, and can be divided into coal-fired, biomass-fired, fuel (gas) and so on according to the fuel. However, the traditional direct-fired hot blast stove is arranged around the burner to make up the air, and the excess air is very large, which affects the temperature of the flame center in the combustion chamber. At present, the hot air load and temperature are controlled by adjusting the supplementary air volume and the fuel volume of the combustion chamber. This kind of control has relatively poor adjustment accuracy, and the control has hysteresis. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem of poor adjustment...
