As preferably, the wall of described flue is arranged to bellows-shaped; Adopt corrugated internal furnace structure, both added radiation and convection heat transfer' heat-transfer by convection area, meet again the needs of flue by free wxpansion after hyperthermia radiation.
As preferably, in boiler body is threaded flue, and the wall of threaded flue is arranged to screw thread form; The screwed pipe of high-efficiency low-resistance replaces traditional light pipe with augmentation of heat transfer, improves the thermal efficiency.
As preferably, described cold doubtful device is provided with fin type condensing tube, and the wall of fin type condensing tube is arranged to the helical fin shape of evagination; The heat exchange of efficient Luo Xuan MOUNTING-EAR sheet pipe, heat-transfer surface is sufficient, and fume side SR is little, meets the requirement of combustor.
In sum, the utility model compared with prior art tool have the following advantages:
The utility model improves insulation construction, the insulation construction be jointly made up of high aluminum wool layer, tinfoil paper layer, high aluminum wool layer forms maintenance to boiler entirety, and tinfoil paper layer prevents heat-preservation cotton moving influence heat insulation effect from having, reflecting part heat loop while stoping heat radiation again, builds optimum thermal environment; The utility model carries out the hermetically-sealed construction of smoke box, and space and the sealant of mazy bending complement each other, and the space of bending blocks flue gas and directly rushes at outlet, defines obstruction to smoke spillage, handles smoke box well and leaks cigarette problem, can prevent quality accident; In addition, the utility model adopts corrugated internal furnace structure, has both added radiation and convection heat transfer' heat-transfer by convection area, meets again the needs of flue by free wxpansion after hyperthermia radiation; The screwed pipe of high-efficiency low-resistance replaces traditional light pipe with augmentation of heat transfer, improves the thermal efficiency; Fin type condensing tube, heat-transfer surface is sufficient, and fume side SR is little, meets the requirement of combustor.
