Structure and advantages of fuel oil (gas) vacuum boiler
This boiler is an internal combustion fire tube full wet back vacuum boiler, the body is mainly composed of combustion chamberconvection smoke tube, vacuum chamber (negative pressure steam chamber), heat exchange tube bundle. Fire-tube boiler has no nitrogen detection dead angle, and all welds can be detected by nitrogen leak detector, eliminating the risk thatthe interna weids of traditiona water-tube vacuum boilers cannot be detected. the vacuum dearee of the furnace body cannot bequaranteed, and the gas leakage cannot be repaired.
The boiler vacuum degree is good, and the heat exchanger structure is advanced
All welds of the vacuum boiler are strictly tested by ammonia vacuum leak detector to ensure the true air tightness of the furnace bodyand the stability of the vacuum. The heat exchanger adopts 304 stainless steel corruoated tube, cancels the traditional "U" tube structureadopts high-pressure heat exchange vessel in-line structure, large heat transfer area, uniform arrangement of heat exchange tubebundles, uniform tube spacinq, no mutual contact, so that the steam and heat exchange tube are fully in contact, increase the heatexchange coefficient, good heat transfer effect, reasonable heat exchanger output design, wll not produce the phenomenon of frequentboiler start and stop, and reduce the mutual friction between the heat exchange tubes, and reduce the violent knocking sound in thefurnace when the boiler starts.
Working principle
The heat produced by the burner is transferred to the intermediate heat media - water, so that it vaporizes and evaporates in the vacuum chamber, the evaporation of negative pressure vapor and heat exchanger in the vacuum chamber heat exchange, the heat transfer to the heat exchanger in the heating or living water, after the exchange of condensed water flows down to the intermediate medium, is heated and evaporated again, repeated cycle.
Safe and reliable
The main boiler always operates under the state of negative pressure, and the phase changes heat. The vacuum degree of the vacuum chamber of the main body is -0.Mpa and the maximum is -0.019Mpa. There is no possibility of explosion and tube explosion and other safety problems, and there is no accident caused by water shortage of the main body. Interlock protection devices such as temperature control of intermediate medium and discharge safety valve between sets ensure the safe operation of the unit from the root.
A multi-purpose machine, at the same time for a variety of pressure hot water
A vacuum hot water boiler can supply heating hot water, sanitary hot water, swimming pool hot water and so on simultaneously or separately. A single loop boiler with separate hot water supply. At the same time supply two or three kinds of hot water for the double circuit or three circuit boiler, and each circuit of the heat exchange equipment can withstand different water pressure, high, middle and low water supply system is very convenient to use.
(0.35-7.0MW) technical parameters of fuel oil (gas) vacuum phase change hot water boiler
Note: 1, The parameters of this table are for reterence and dimensional chances due to desian updates wll not be noticed.
2. Fuel consumption according to the low calorific value of light oil 10290kcal/kq, natural gas 8600kcal/Nm3.
3, Heatina and domestic water can choose one of the functions as a single-circuit boiler, and both have double-circuit boilers.
5. Domestic water volume according to (10-60· C)4. If you need 1.0Mpa water supply pressure, special instructions when ordering.
