Hot blast stove

Abstract

The invention provides a hot blast stove, which includes a casing, a combustion chamber, a cold air outlet, a blower, an air distribution cylinder, a high-pressure fan, a hot air outlet, a flue, a combustion ash outlet, a combustion-supporting wheel, and a heat storage device. chamber, the shell is connected to the front and rear of the combustion chamber as a whole, the bottom of the combustion chamber is provided with a support column, and the center of the bottom of the combustion chamber is also provided with a combustion ash outlet, and the combustion ash outlet extends to Outside the casing, a valve plate is provided at the mouth of the ash outlet, and an air distribution tube and a flue are provided on the top of the combustion chamber. The front and rear parts of the flue are connected with the casing as a whole. A cold air outlet is provided between the air duct and the flue, the mouth of the cold air outlet is provided with a blower, the mouth of the air distribution cylinder is provided with a high-pressure fan, and the inner center of the combustion chamber is provided with a combustion-supporting wheel. Heat storage devices are provided on both sides of the combustion chamber. The beneficial effect of the invention is that the fuel burns more completely and the effective heating rate is further improved.

Description

technical field [0001] The invention belongs to the field of heat energy equipment, in particular to a hot blast stove. Background technique [0002] As a thermal power mechanical hot blast stove, it began to be widely used in my 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] Through long-term production practice, people have realized that only by using hot air as the medium and carrier can the heat utilization rate and thermal work effect be greatly improved. However, there are still some problems in existing hot blast stoves. For example, when coal or biomass fuel is used as direct fuel, there is often a large amount of waste of fuel due to incomplete combustion; Cause problems such as energy waste. Contents of the invention [0004] The object of the present invention is to provide a hot blast stove with simple structure, simple operation and more complete f...
