Gas hot water condensing units for heat pump boiler condensate recovery What is the significance? With the boiler industry technology research and development to constantly improve, a lot of gas hot water boilers are fitted with a condensing device, and the role of one of the condensing device can help us to condensate recovered. So, in this process there will be many users have doubts, what is the significance of gas condensate recovery hot water boiler exactly? Xiaobian below take you to do a simple understanding. (1) containing a higher heat condensed water, be recycled, one can reduce the low temperature water up into the boiler, to save fuel; it can also improve the thermal efficiency of the boiler to a certain extent, it can be said to serve two purposes. (2) In general, the condensation is relatively high in calories, which will be relatively low oxygen content, be reasonably recycling, recycling, boiler corrosion hazards can be reduced to some extent; Further, temperature condensate is discharged rush , it can also cause damage to the sewer. In short, gas hot water boiler condensate recovery, either for energy saving boilers, hot water treatment or to enhance the efficiency of boilers and other costs will be more favorable.
First, preparatory work before the pressure test gas steam condensing units for heat pump boiler 1, internal cleaning and inspection of the surface of the test portion. 2, to check whether or pipe clogging. 3, installed by a qualified legal department check the pressure gauge (not less than 2), after a year to conduct a check by the legal department. 4, close the valves on the gas-fired, the safety cover can be used to seal the valve seat, into the water from the inlet pipe at a locus (water temperature of 20 ~ 70 ℃), and the vent valve was opened evacuated vent valve was closed after the water to be filled . Ambient temperature should be above 5 ℃, or measures must antifreeze; and to prevent surface condensation boilers. 5, the pump inlet pressure test stand can be connected after a pump pressure. Second, a water pressure test gas steam boiler, gas steam boiler test pressure is 1.65MPa. 2, the water pressure should rise slowly, when the pressure rose to the working pressure should be suspended boost, check for leaks or anomalies, and then rose to the test pressure, maintained at this pressure for 20 minutes, then again down to work check the pressure, the pressure should remain unchanged during the inspection. Third, gas steam boiler pressure test security measures and precautions 1, is strictly prohibited flange bolts tightened when the pressure exceeds 0.3MPa. 2, the hydraulic pressure test, the scene should be specially marked to prevent accidental danger. 3 can not stand directly in front of the valve flange and the test weld. Fourth, the gas steam boiler hydrostatic test acceptance criteria 1, and no water mist on the walls of the pressure receiving element and the weld metal. 2, after the pressure test found no residual deformation.
Why do many service sites choose condensing condensing units for heat pump boilers?
Condensing boiler is the so-called new generation boiler, it is necessary to use this kind of condensing boiler in heating or hot water supply, and the working efficiency of standard condensing boiler is very high. To meet the requirements of the efficiency of each site, the condensing boiler emerges as the times require, then why do many service sites choose the good after-sale condensing boiler?
1, designers of highly condensing boilers with strong operating performance will use modern software to assist in their work according to the requirements of use, and at the same time should conduct practical operation simulations in accordance with advanced design systems. Therefore, many operators say that it is easy to operate in the late stage of condensing boiler because the product design makes it have good operation performance, and the automation degree of condensing boiler is relatively high, which can almost realize unmanned operation.
2, strong durability, in view of the special working environment and operational requirements of professional condensing boilers, it is necessary to carry out a second durability analysis in production design, including material selection of condensing boilers and their later process technology and construction planning. Cutting and welding work is also responsible for cutting and welding. After completion of production, the condensing boiler needs to be polished and sprayed, so that its service life can be greatly improved.
3, the working environment of the weather-resistant / environment-resistant condensing boilers is generally worse. In some condensing boilers, there are not only a lot of wet gas but also many chemical corrosion substances, and the daily working frequency of the condensing boilers is higher. Therefore, it puts forward a new and higher requirement for its weatherability and environmental resistance. The condensing boiler can avoid corrosion through professional design. Therefore, the professional condensing boiler effectively evades the late fault in the later stage, which makes the service life of the condensing boiler longer and the failure rate lower.
Fast Boiler Co., Ltd. is a really truly think about your clients practical solutions to business problems, this recommendation after this water-tube condensing units for heat pump boilers put into use, the quality inspection departments, the nitrogen oxide emissions, soot and other indicators They are in line with national standards, but also very full of fuel combustion, high thermal efficiency, saves us a lot of fuel costs. This cooperation, I am very satisfied. --customer feedback
