The DHL biomass corner tube chain grate hot water boiler introduces the technology of the GEF project, and based on the domestic and overseas angle boiler products and technology research, according to China's biomass chain grate technology development characteristics and market demand for independent innovation design, is Reliable water circulation, high-efficiency combustion, and low-pollution emission of large-capacity fuel-fired grate grate boiler energy-saving products.
The boiler is composed of a boiler barrel, a furnace water wall, an outer down pipe, a large scale chain grate, two sets of economizer and a tubular air preheater. The downcomer of the boiler is arranged on the four corners of the boiler, not only as a water circulation channel, but also as a supporting framework for the boiler. The boiler tube is external, the furnace is completely closed membrane wall structure, the convection heating surface adopts gas surface tube structure, no steel frame, the water cycle is unique and safe, and it starts quickly. The boiler is designed in double layers, and can be arranged in one layer. Two vertical coal loader can be used separately for coal and coal transportation. The boiler body adopts a lower support, a suspended ceiling, a heat-resistant concrete light furnace wall and a furnace top, and is supported by eight columns.
DHL biomass corner tube chain grate hot water boiler has high thermal efficiency, low operating cost, long-term trouble-free operation, low fume and dust emission at the boiler outlet, light weight, low investment in infrastructure, and shipment from the factory. It has a small on-site installation workload and a short installation period. Such characteristics are the latest alternatives to large-capacity hot water boilers in China.
