coal-fired (gas) hot-blast stove is my company and XI ' an Jiaotong University, China ship building industry Corporation, Shanghai Industrial boiler Research Institute, University of mining and technology. joint development and design after many upgrades have reached advanced level at home and abroad, stove , coal stove, food hot-air furnace, drying furnace .   breed stove. Taikang, Henan province boiler manufacturing co., Ltd. was founded in the late 70 age early, was the Midwest one of the largest boiler manufacturer, State-level high-tech enterprise, first through industry first, Henan province A boiler D1 , and D2 pressure vessel of modern enterprises, national service demonstration enterprises, is national hot-air furnace draft units. this product is made of long spiral groove heat exchange technology, integration of combustion and heat exchange design, compact structure, reasonable layout, heat intensity, heating up fast, high heat efficiency. with a small footprint, easy installation and operation, clean hot air (hot air flue gas along the road), stable performance and so on. using indirect heat transfer technology of the hot stove, and clean air as the heat transfer medium, for a variety of industries with a heat process provides the ideal direct sources of heat, heating temperature is divided into low-temperature five degrees centigrade, medium temperature of 120-330 ° c, high-temperature 60-120 ° c, in three grades, and customers can be freely chosen according to technological requirements. which are widely used in chemical, food, medicines, tobacco, ceramics, construction materials, packaging materials and various materials, such as coal drying, spray and dehydration. can also be used for tall building, Auditorium, farm sheds, barn and other buildings for heating, as well as places such as underground mining, underground engineering, coal mine heating and dehumidifying.                                                           

first, working principle and main equipment characteristics:
stove one combustion chamber and heat exchanger, full steel sleeve longs multilayer spiral groove type structure, its lower part of the burners for the combustion chamber, and around the upper ring heat exchangers, air and flue gas is dual backhaul, its heat. in order to improve the thermal efficiency, long spiral groove heat exchange technology and theory of turbulence, thickness of thin laminar flow, exchange of Rotary air and flue gas during the walk continues, has greatly enhanced the effect of heat. the main processes: high temperature flue gas generated in the coal-fired furnaces, fan into the smoke ring, and outside air after the heat exchanger, flue chimney exhaust, cold air blown into the furnace casing by blower, lateral flow into furnaces air top ring, by the hot air outlet piping supply of clean hot air equipment.
main equipment: stove main part on gas ontology, grates, reflection panels, hot-air and flue gas ducts, chimneys, fan (with valve), blowers (with valve) , instrument valves and other components.
II features:
a, coal, wood, oil and gas as fuel. b, to clean the hot air drying medium, no pollution.c, low energy consumption, high thermal efficiency.d, automatic measurement and display.
e, the operation is simple, easy to use, Equipment all domestic, its performance index achieves the domestic advanced level.
