Description
Technical field
The utility model relates to a kind of hot-water heating system in heat supply process field, particularly a kind of condensation indirect heat exchange heating system.
Background technology
At present, hot-water heating system mainly adopts normal-pressure hot-water boiler, for work, life provide domestic water, the primary structure of hot-water boiler comprises body of heater and places the interior drum of body of heater, the top of drum is connected with expansion tank, the bottom of drum inner chamber is provided with the combustion chamber, the smokejack that the body of heater top links to each other with the combustor tail smoke box is provided with condenser, be provided with number row finned tube in the condenser, to reclaim the heat in the smoke evacuation, reduce exhaust gas temperature, fresh water is flowed through and is made a gift to someone after the finned tube temperature of condenser is raise in the drum simultaneously.The weak point of this heating system is: the water after the heating is sent to heat supply point through pipeline and uses, fresh cold water source constantly replenishes in the body of heater, owing to be rich in calcium, magnesium ion in the fresh water, has certain rigidity, after working long hours, when constantly heating fresh water, the fouling meeting in the drum is serious day by day, and incrustation scale has very high thermal resistance, can reduce heat transfer efficiency greatly, not only cause energy waste, and make heating surface can not get good cooling, have potential safety hazard.Must blowing out carry out scale removal when fouling is heavier, scale removal not only needs man-hour, increases use cost, and no matter is mechanical descaling or chemical cleaning, all can cause certain damage to drum.In addition, the dissolved oxygen in the fresh water has corrosiveness to steel, also can shorten the service life of boiler.
Also have a kind of heating system, the condenser water inlet links to each other with boiler drum bottom by circulating pump, and the condenser delivery port links to each other with the drum top, and promptly hot water in the condenser and drum form circulation.It is less that such heating system enters the water temperature and the temperature difference between the exhaust gas temperature of condenser, influenced the waste heat recovery effect of condenser.
The utility model content
At existing unpressurized hot water boiler's above shortcomings, the utility model provides the condensation indirect heat exchange that a kind of UTILIZATION OF VESIDUAL HEAT IN is effective, the thermal efficiency is high heating system.
For solving above technical problem, a kind of condensation indirect heat exchange heating system provided by the utility model, comprise hot-water boiler, hot water feeding pipe and hot water return pipe, hot-water boiler comprises body of heater and places the interior drum of body of heater, the top of drum is connected with expansion tank, the bottom of drum inner chamber is provided with the combustion chamber, the smokejack that the body of heater top links to each other with the combustor tail smoke box is provided with condenser, be provided with number row finned tube in the condenser, the top of drum inner chamber is provided with heat exchanger, heat exchanger comprise that number row is that array distributes and through the drum length direction heat exchanger tube, the two end plates of heat exchanger is respectively equipped with exchanger head outward, exchanger head is provided with heat exchanger water inlet and heat exchanger delivery port, the condenser water inlet links to each other with described hot water return pipe, the condenser delivery port links to each other with the heat exchanger water inlet, and the heat exchanger delivery port links to each other with described hot water feeding pipe.
Compared with prior art, the beneficial effect that the utility model is obtained is: the back-end ductwork of boiler is provided with condenser can reclaim waste heat in the smoke evacuation, reduce exhaust gas temperature, make the water at low temperature that enters heat exchanger obtain preheating, in the condenser between high-temperature flue gas and the hot water backwater temperature difference bigger, good effect of heat exchange; Connect with heat exchanger in the water route of condenser, water at low temperature enters indirect that heat exchanger continues to be subjected to stove water again after the condenser preheating become and meet the hot water that heating system requires; Being subjected to the direct-fired water in combustion chamber in the drum is closed cycle, consumes seldom, can not improve dissolved oxygen and hardness of water in the drum because of a large amount of fresh waters that replenish.
