Coal gas temperature-adjusting burner with diluted wind

The invention relates to a gas thermoregulation burner gun self provided with dilution wind, of which the airflow temperature at an outlet is adjustable within 100 to 1000 DEG C and which is widely applied to the low temperature roasting, heating and drying for materials; the invention aims to solve the problems that the 'outside furnace cyclic heating system' is complicated in equipment, huge in investment and large in land occupation, the invention makes use of the burner gun combustion system to solve problems of two systems of combustion air supply needed for normal combustion of gas and dilution air supply needed for coldness; the burner gun combustion chamber is provided inside with four rows of air orifices respectively; the first row of air orifices are monitoring holes and lightening holes of burner gun; the second row of air orifices are one-time air orifices; the third row of air orifices are two-time air orifices; the fourth row of air orifices are three-time air orifices; dilution wind orifices are arranged along edges of an excircle of the outlet of the burner gun combustion chamber; the mixed gases with relatively large temperature range are generated by adjusting the supplied quantity of gases and the air quantity, which contributes to meeting the technical requirements of the roasting and drying of materials with different temperature requirements.
