Fuel gas (methanol) drying hot blast stove

Product Introduction

LRFThe series of hot air stoves has a new generation of heating products jointly developed and designed by our company and China Shipbuilding Heavy Industry Corporation. 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 transfer 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 blast 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 low temperature（80~150℃), medium temperature（200~300℃), high temperature（400~550There are three levels (℃), and customers can freely choose according to the requirements of the drying process. This product is widely used for drying, spraying, and dehydrating various materials such as chemicals, food, medicinal herbs, tobacco, ceramics, and building materials. It can also be used for heating in buildings such as factories, auditoriums, sheds, and livestock houses, as well as for dehumidification or heating processes in underground mining areas, underground engineering, and other places.

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: Oil and gas generate 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 shell of the hot blast stove by the blower, flows into the air ring outside the furnace through the top, and is supplied to the equipment that needs clean hot air through the hot air outlet pipe.

2Main equipment
