Described condenser comprises the condenser coiled pipe of gas approach, exhanst gas outlet, condenser header and upper and lower adverse current in-line arrangement.Further, described condenser coiled pipe adopts ND steel matter, and outer tube wall is arranged helical fin with extended surface.
Compared with prior art, the utility model has following features:
(1) pressurized firing is realized, the thermal efficiency is high: burner hearth surrounding is full film type wall sealing, save brickwork and the partition wall of boiler, ensure that the sealing property of burner hearth entirety, without leaking out, thus realizing pressurized firing, make furnace flame degree of filling good, heat exchange is abundant, and heat loss is little, can without the need to separately putting air-introduced machine;
(2) modularized production can be realized, self-contained convenience;
(3) fuel element and convection heating surface unit are divided into two separate modules, had both retained the advantage of conventional self-contained boiler, the restriction of conventional self-contained boiler load can be broken through again, to larger parameter and load development;
(4) the coiled pipe tube wall of economizer and condenser arranges helical fin structure, contributes to improving heat exchange efficiency, reduce the exhaust gas temperature of condenser offgas outlet, the latent heat of vaporization of steam in recovered flue gas, improves boiler thermal output as far as possible;
(5) external economizer, volume is little, is convenient to install change and regular maintenance;
Boiler thermal output of the present utility model is higher, and former corresponding boiler thermal output basis improves about 7%, and it is substantially constant to control the maintenance of boiler resistance, and overall structure is compacter, easy to utilize.
