Description

Small atmospheric hot-water boiler

Technical field

The utility model is related to boiler technology field, more particularly to a kind of horizontal small atmospheric gas, oil burning boiler.

Background technology

Small atmospheric combustion gas, oil-fired water-boiler are suitable for the uses such as family, hotel, villa, bank, midget plant, tool Occupy little space, using it is easy to operate the features such as.Prior art normal-pressure hot-water boiler stove inner water sleeve is generally set using single cycle Meter, and flue, flue are straight barrel type design, inner space is big, heating surface area is small, and high-temperature flue gas flow is short, and the thermal efficiency utilizes Insufficient boiler heating is slow, causes water in stove only by 1 heating, uneven heating, heat energy loss is serious, and leaving water temperature is unstable Fixed, floss hole temperature drift, heat utilization rate is low, causes energy waste, and not environmentally.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of reasonable design, that the thermal efficiency is high and discharge capacity is few is small-sized Atmospheric gas, oil-fired water-boiler.

The technical solution adopted in the utility model is：A kind of small atmospheric hot-water boiler including furnace body, is arranged on the stove Combustion chamber, flue in body and go out flue and be arranged on the smoke evacuation room of furnace body one end, the combustion chamber is compact arranged Endless solenoid structure, the tubulose flue that setting annular spread arranges in the helix tube periphery, one end of the flue With the combustion chamber, the tubulose for annular spread being set to arrange between the flue and the furnace body goes out flue, described The one end for going out flue is connected with the flue, it is described go out flue the other end connect the smoke evacuation room, the furnace body with it is described Water jacket is formed between combustion chamber.

Further, the flue quantity is 34~38, and the flue is bellows structure；It is described go out flue number It is 34~38 to measure, it is described go out flue be bellows structure；The upper of furnace body is additionally provided with expansion tank.

The beneficial effects of the utility model are：Furnace body inner combustion chamber, flue and go out flue using three cycle convolution layout, So that the heat 90% that burning generates is absorbed by the water in three cycle gyrotron roads, the water in water jacket can be made to be heated evenly, more Be conducive to heat transfer.Combustion chamber uses endless solenoid structure, and flue uses bellows structure with flue quantity is gone out, further Too high boiler thermal efficiency.Upper of furnace body has also been devised expansion tank and is recycled to the waste heat of discharge, can incite somebody to action Floss hole temperature control not only ensures at 50 DEG C or so boiler energy safety and steady run, but also improve the thermal efficiency, save the energy and Protect environment.
