Abstract
The utility model relates to a biomass generating steam water system possessing a function of smoke waste heat recovery. A conventional technology employs a smoke venting standard of an original coal-fired boiler as a boiler smoke venting temperature, thereby resulting in the insufficient utilization of the heat energy of smoke venting, comparatively low capacity and parameters of a biomass generator set, and slightly low overall energy efficiency of a power plant. The biomass generating steam water system comprises a condensation type condensed water heater, which comprises a housing. An exchange cavity and a hydrophobic cavity, which are connected vertically, are disposed in the housing; a smoke outlet of a biomass boiler is connected with the exchange cavity; a vertically arranged condensed water coiler is disposed in the exchange cavity; a condensed water outlet and a condensed water inlet, which are arranged vertically, are disposed on a housing of the exchange cavity; a housing of the hydrophobic cavity is provided with the smoke outlet and smoke condensed water outlet, which are arranged vertically; the condensed water outlet is connected with a deaerator; and the condensed water inlet is connected with a steam seal heater. The biomass generating steam water system enables timely drainage of smoke condensed water, improves anti-dust deposition performance and decay resistance of the heater and enables the saved back heating extraction steam to be used for power generation completely.
