Among Fig. 2: down-comer 16, decline case 17, drum 18. The present invention is in water circulation system In be designed with tedge, indirect condenser 1, filling valve 4 and steam supply pipe 5. Tedge is made up of epimere tedge 7, hypomere tedge 12 below the waterline and the partial circulating mouth 9 between them. Epimere tedge 7 and hypomere tedge 12 communicate. Indirect condenser 1 utilizes the backwater of hot system to carry out indirect heat exchange at the top of epimere tedge 7, with the vapour in the epimere tedge 7, the steam-condensation of aqueous mixtures. At furnace roof filling valve 4 and steam supply pipe 5 are installed, an end of steam supply pipe 5 communicates with drum, and the other end communicates by the root of filling valve 4 with epimere tedge 7. When in the epimere tedge 7 when the boil-off amount is inadequate, can replenish by blowdown pipe 5 and filling valve 4, the filling amount is by filling valve 4 control. Like this, because the density of hot water of supplying with the user is greater than the density of the vapour in tedge 7 and 12, aqueous mixtures, thereby produce circulating head, realize to using the hot-water heating system heat supply.
Purpose of the present invention can also realize by following measures:
In order to adapt to various conditions, realize relying on oneself the hot-water heating dedicated water circulatory system, tedge can also be taked various ways: adopt single tube generally speaking.When needs satisfied big flow, hypomere tedge 12 as shown in Figure 2 can be two-tube or multitube parallel or series connection, and partial circulating mouth 9 can be two or more branches and adapted this moment.Hypomere tedge 12 can also be designed to horizontal component and be heated in stove, and its vertical component can be arranged in outside the stove.Epimere tedge 7 also can be designed as two-tube or multitube simultaneously, divides the road direction user heating.When epimere tedge 7 is enough to meet the demands, can also exempt from the section of setting tedge.The also section of setting tedge 12 only as required simultaneously.
