Described upper furnace is provided with the crust block pipe, and described crust block pipe is provided with groove separator, and described groove separator is two and is the skewed flat steel bar that is welded in crust block pipe outer wall.
Described body of heater is provided with back-end ductwork, is provided with the louvered separator in the described back-end ductwork, and described louvered separator is that three roads are parallel to each other and the staggered channel-section steel of installing.
Operation principle of the present utility model is: during boiler operatiopn, backwater by the anterior water inlet collection of boiler drum case after backwater inlet tube and backwater distributing pipe enter drum, enter the burner hearth front and back walls respectively by down-comer, left and right wall forms a natural water-flow circuit, water through heating is introduced drum by drum rear portion drum centerline, the front and rear part is separated by dividing plate in drum, and leaves the boiler internal water circulation channel, and hot water is drawn drum by the drum top through collector pipe and hot water fairlead.The hot water that is come out by drum enters convection heating surface next part case, further enters water outlet collection case after the heating through the coiled pipe heating surface, externally exports hot water.
The utility model water circulation system is divided into two covers: i.e. the natural water-flow circuit system of burner hearth part and the pressure water circulation system of coiled pipe convection heating surface.So both guaranteed water circulation reliability, reduced boiler export cigarette temperature again, controlled the cold end corrosion problem in the boiler operatiopn again effectively simultaneously, reached efficient. purpose of energy saving.
The utility model adopts coiled pipe convection bank structure from the structure and the water endless form of heated surface at the end of boiler, increases the nature water-flow circuit separately, has guaranteed the security reliability of water circulation.Abandon flag formula heated face structure, thereby reduced manufacturing cost, reduced maintenance cost, guarantee safety, the energy-saving and environmental protection of product simultaneously.
In addition, the utility model has increased the louvered separator at crust block pipe place, has improved separative efficiency; Back-end ductwork has increased groove separator, further reduces the original dust exhausting concentration of boiler.
The utility model has not only been guaranteed high efficiency boiler, energy-conservation characteristics, changes the coiled pipe structure into by the flag comb simultaneously, has simplified the design of product, be convenient to implement to produce in batches, reduce labour intensity, adopted nature water-flow circuit mode simultaneously, guaranteed the security of water circulation.The twice dust arrester, i.e. the setting of louvered separator and groove separator has reduced original dust exhausting concentration, has improved the thermal efficiency of boiler, has reduced the boiler maintenance cost.
