Description

Phase transformation-liquid bath type gas fuel hot-water boiler

Technical field

The utility model relates to a kind of boiler, particularly a kind of phase transformation-liquid bath type gas fuel hot-water boiler.

Background technology

Hot-water boiler is widely used in industrial production and the daily life, for example is used for regional heating, hot water station, center etc.Since hot water heating than the thermal loss of steam heating lack, safety, maintenance cost is low, so China is greatly developing hot water heating at present, in the hope of replacing steam heating.Yet, in the many areas of China,, and do not soften processing under a lot of situation, the easy scaling of heating surface, perishable, life-span weak point when adopting the ordinary hot homogeneous solution-type reactor because hardness of water is higher.Existing Phase transformation boiler, though have non-scaling in the stove, heat-transfer surface not can by dry combustion method, long service life, can be with the effective advantage such as isolation of heat exchanging fluid, but existing this class boiler controllability is poor, automatic regulating system is required high, the processing and manufacturing difficulty, safeguard complexity, so also be difficult to extensive use.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of existing hot-water boiler, the variation of dependence heating agent liquid level and the variation of heat-transfer surface heat-transfer character of using phase transformation-liquid bath type heat exchanger keep metastable this characteristic of Heat Room internal pressure automatically, and a kind of phase transformation-liquid bath type gas fuel hot-water boiler is provided.

The technical solution of the utility model is based on the technology of 03232492.8 phase transformation-liquid bath type heat exchanger patent applied for, in the pipeline of heating agent, be in series with Heat Room successively, air-stopper, the U-shaped pipe, liquid reserve tank, floating cover, vent valve and safety valve are equipped with in the Heat Room top, liquid level gauge is equipped with in the side, the Heat Room internal upper part is equipped with the heated fluid heat-transfer surface, the bottom is equipped with gives the hot fluid heat-transfer surface, liquid reserve tank is positioned at the Heat Room over top, floating cover is positioned at the liquid reserve tank top, be characterized in, the heated fluid heat-transfer surface that the Heat Room internal upper part is equipped with is made up of two cover coil pipes, what the Heat Room bottom was equipped with gives the hot fluid heat-transfer surface by smoke pipe, the flue and the chamber of strile-bacing are formed, the arrival end of flue is equipped with burner, and the outlet side of smoke pipe is equipped with chimney, is equipped with explosion proof door between flue and chimney.Fuel and air spray in the flue through burner and burn, the flue gas that burning is produced is the hot fluid that gives in the utility model, give flow of heated fluid and behind flue, the chamber of strile-bacing, smoke pipe, chimney, arrange to atmosphere, give hot fluid in flue based on the radiation heat release, in smoke pipe based on convection heat transfer.Heated fluid in the utility model is the water of two kinds of different parameters, flows through two cover coil pipes respectively, discharges boiler after temperature raises.

Because the utility model is a kind of phase transformation-liquid bath type hot-water boiler that uses gas or liquid fuel, by heating agent with the heat exchange of " phase transformation-bath of liquid " mode, therefore, not only has non-scaling in the stove, heat-transfer surface can be by dry combustion method, long service life, heat exchanging fluid effectively can be isolated etc. Phase transformation boiler common advantage, and overcome some shortcomings of existing Phase transformation boiler again, it is good to have a self-tuning performance, it is stable to keep the Heat Room internal pressure automatically, safe, do not need to dispose air-extractor, the heating agent loss is few, need not to adopt unique advantages such as extra anticorrosion maintain measure between lay-off period.
