Xinxiang Boiler manufacturer express As the boiler adopts needle tube heat exchange elements and vertical modular layout structure, under the same heat exchange area, the overall investment costs of equipment, installation and infrastructure are greatly reduced. In terms of equipment installation and layout, Waste heat boiler manufacturer It provides more space for users.

Light weight and small volume: due to the vertical layout, the reverse heat exchange between flue gas and water is realized, and the volume and weight are greatly reduced.

Wear resistance: the needle shaped tubes are arranged in sequence, and the needle rib divides the space into several small areas, which has a flow sharing effect on the air flow. Compared with the smooth tubes and spiral fin tubes arranged in staggered arrangement, the wear life is 3~4 times higher under the same other conditions.

Low energy consumption: needle pitch, tube pitch and arrangement form of needle shaped tubes are important design parameters of waste heat boiler. No matter whether the boiler scours the tube bundle horizontally or longitudinally, all the needle shaped extended surfaces are scoured by the transverse turbulence of flue gas. The airflow forms a symmetrical steady vortex and backflow area on the back of the cylinder with needle ribs, and the thermal boundary layer is constantly destroyed and re formed, thus making the entire heat exchange boundary layer thinner, reducing the thermal resistance and increasing the heat transfer coefficient.

Sealed well: all butt welds are welded by argon arc welding, and the welding quality is higher than that of manual welding.

Flue type waste heat boiler : Water tube waste heat boiler whose tube bundle is set in the furnace made of refractory materials. The structure is very similar to that of ordinary combustion boilers. High temperature gas passes through the furnace (or flue) and indirectly exchanges heat with the water in the tube bundle to generate steam. The steam water mixture rises along the tube bundle and enters the upper and lower drums. After steam separation, the water again enters the lower drum along the unheated downcomer to form a natural cycle. It can be matched with small steam turbines for power generation.
