working principle

The combustion chamber and heat exchanger of this hot blast stove are integrated, adopting a multi-layer sleeve structure made of all steel plates. The lower part of the furnace core is the combustion chamber, and the upper and surrounding parts are circular heat exchangers. The air and flue gas are both double return and exchange heat in their respective paths. In order to improve thermal efficiency, multi head spiral groove heat transfer technology and turbulent flow principle are adopted to reduce the thickness of laminar flow, so that air and flue gas continuously exchange directions during movement, greatly enhancing the heat transfer effect.

Main working process: Coal combustion generates high-temperature flue gas in the furnace, which enters the smoke ring under the action of the fan, exchanges heat with the outside air, and is discharged from the chimney through the flue. Cold air is blown into the outer shell of the hot blast stove by the blower, flows into the air ring outside the furnace through the top, and is supplied to equipment that needs clean hot air through the hot air outlet pipe.

Performance characteristics of WYH series hot blast stove:

This product adopts multi head spiral groove heat exchange technology, integrating combustion and heat exchange design, making the product compact in structure, reasonable in layout, high in heat exchange intensity, fast in temperature rise, and high in thermal efficiency. It has the characteristics of small footprint, easy installation and operation, clean hot air, and stable performance. This hot air stove utilizes indirect heat transfer technology, using clean air as the heat transfer medium, to provide an ideal direct heat source for heating processes in various industries. The heating temperature is divided into three levels: low temperature (80~150 ℃), medium temperature (200~300 ℃), high temperature (400~550 ℃), and customers can freely choose according to the requirements of the drying process.

1. Using coal as fuel.

2. Using clean hot air as the drying medium, pollution-free.

3. Low energy consumption and high thermal efficiency.

4. Automatic temperature measurement and display.

5. Easy to operate, convenient to use, all supporting equipment is domestically produced, and its performance indicators have reached the level of advanced national products.

This hot air stove is widely used as a drying heat source for drying, printing and dyeing, baking paint and other materials such as grains, medicinal herbs, various agricultural and sideline products, and various materials. It can also be used for heating plastic greenhouses in high-rise factories, as well as dehumidification and heating in underground mines, underground engineering and other drying occasions. The high-temperature hot blast stove is particularly suitable for production in industries such as metallurgy, chemical engineering, ceramics, forage, and feed due to its hot air reaching up to 600 ℃, and its benefits are particularly significant.
