DHL Series Biomass Fired Corner Tube Boiler

The DHL series biomass fired corner tube steam boiler is a high-efficiency, large-capacity boiler designed with advanced membrane water wall technology adapted from power plant boilers. It features a unique corner tube structure, where four large-diameter downcomer tubes are positioned at each corner to serve as both support and part of the water circulation system. This bulk-type boiler adopts a fully enclosed membrane wall and flag tube convective heating surface, ensuring compact structure, quick temperature rise, and superior sealing performance. The combination of natural and forced water circulation guarantees safe, stable, and reliable operation. The self-supporting furnace and convection heating surfaces reduce steel consumption and lower civil construction and maintenance costs. Capable of burning a wide range of biomass fuels — including wood chips, rice husk, bagasse, coconut shell, peanut shell, and cotton shell — this boiler is an environmentally friendly alternative to traditional coal-fired systems.
