LRF series high-temperature combustible biomass is a multi-layer, multi-return structure, and the hot air temperature can reach above 600C, which is the first product in China. In the Z / DLRF series, the low temperature hot blast stove is a new type of vertical boiler. For the first time, the multi-head spiral groove heat exchange technology is used. The structure is compact, the form is novel and reasonable, the thermal strength is high, the temperature rises quickly, the efficiency is high, the installation and operation are convenient, and the performance is Stable and economical, it has reached a professional level.

working principle

Working principle of RF series high and medium temperature hot blast stove:

The combustion chamber and heat exchanger of the hot blast stove are integrated into a whole, adopting a full-steel multi-layer sleeve structure. The lower part of the furnace core is the combustion chamber, and the upper and surrounding are circular heat exchangers. The air and flue gas are double-return. The channel performs heat exchange. In order to improve the thermal efficiency, the multi-head spiral groove heat exchange technology and turbulent flow principle are used to reduce the laminar flow thickness, so that the air and flue gas can continuously exchange rotation directions during travel, which greatly enhances the heat exchange effect. Main working process: Coal combustion generates high-temperature flue gas in the furnace, enters the smoke ring under the action of the fan, and after exchanging heat with the outside air, it is discharged from the chimney through the flue, and the cold air is blown into the shell of the hot blast stove by the blower and passes through the furnace. The air ring that flows into the outer side of the furnace top is supplied by the hot air outlet pipe to the equipment that needs clean hot air.

Performance advantage

a. The hot blast stove uses coal as fuel.

b. The hot blast stove uses clean hot air as the drying medium without pollution.

c. The hot blast stove has low energy consumption and high thermal efficiency.

d. Automatic temperature measurement and display of hot blast stove.

e. The hot blast stove is easy to operate and easy to use. All supporting equipment is domestically produced, and its performance indicators have reached professional standards.
