Blowing-type high heat stove

Abstract

The invention relates to a blowing-type high heat stove. The high heat stove is composed of a stove body, a stove ring, a combustor, an ignition device, a blower and a control valve. The combustor comprises a stove chamber, a fire-resistant stove ring and a combustion hole. An extension pipe is arranged at the lower end of the stove chamber. The control valve comprises a power switch, a pulse switch, an air inlet valve and an air door adjusting hand wheel. The blower and the stove chamber are in series state through a ventilation pipe. The air inlet valve is connected with the ventilation pipe through an air supply pipe and liquefied gas is mixed into the extension pipe. The air supply pipe and the ventilation pipe are connected into an integrated structure. An ignition central pipe is arranged in the stove chamber and the extension pipe. An ignition porcelain needle goes through the ignition central pipe. After the above structure is modified, the air supply pipe and an air inlet pipe are integrated, liquefied gas go to the air inlet pipe first, after mixing, the mixed gases go into the extension pipe for full mixing again. The mixed fuel gases have high flame heat energy, can be burnt fully,and energy saving is achieved. In addition, liquefied gas goes into the ventilation pipe first, no gas leakage phenomena are generated, and dangers are avoided.

Description

technical field [0001] The invention relates to a stove, in particular to a gas-fed blast type blast furnace. Background technique [0002] At present, most of the blast furnaces used in the market use blowers to assist in enhancing the combustion firepower. The purpose of mixed combustion, but there is a risk of air leakage. The ignition device of the burner is arranged crosswise with the burner, and is input in parallel with the liquefied gas intake pipe. The ignition switch and the intake valve are set at the same position, which may easily cause ignition failure. If The intake pipe produces air leakage, and the arrangement of the ignition device and the intake pipe in parallel is likely to cause danger. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving, simple-structured, safe and reliable blast-type blast furnace. [0004] In order to solve the above-mentioned technical problems, the present...
