ul certificate standards heat pump boiler
Excessive moisture content in steam ul certificate standards heat pump boiler steam boiler steam system of hazard in the event of excessive steam water content, will constitute a steam system damage. Steam boiler system in major damage to wet steam are: 1, water droplets suspended in the steam pipeline corrosion can drop life. Replacement pipe is not as long as the cost of materials and labor, and you want some pipeline closed for repairs, it will bring some loss of production. 2, the steam contained in the steam boiler system, water droplets can damage (corrosion of the valve seat, the valve body) the control valve, so that the effect of lost, and eventually damage the quality of the goods. 3, the steam contained in the water droplets will collect on the exterior of the heat exchange water into a thin film growth. 1mm thick film of water corresponding to 60mm of iron / steel sheet or 50mm thick copper plate heat transfer, this layer of water film to change the appearance of the heat exchange coefficient of the heat exchanger, the heating time is extended, decreased production capacity. 4, wet steam with decreased total gas heat exchange device power. Water droplets occupy valuable space means boring full steam vapor will be taken to effect heat transfer. 5, the wet steam in a steam boiler system in concealing mixture of fouling in the heat exchange outer, heat exchange will decrease power. Heat exchange outer layer scale is not the same thickness, which causes different thermal expansion, a crack will occur on the outer heat exchanger. The material is heated from the condensate mixed with leak cracks, loss soiled condensate, will bring about high costs. 6, the wet steam concealing mixture control valve and steam trap fouling, will affect the operation of the valve, to add the cost of repairs. 7, wet steam boiler system, steam heating the product mixture enters the concealing eruption of steam directly, if the product requires high hygiene standards fit, becomes contaminated waste products will not be sold. 8, some processing technology is not wet steam, wet steam will eventually affect the quality of the goods. 9, in addition to the influence of the apparent power of the heat exchange outer wet steam, wet steam concealing will constitute excess water trap and condensate recovery system overload. Traps overload will condensate back, if condensed water vapor occupies space, which will reduce production capacity of processing equipment, during this period will ultimately affect the quality of the goods. 10, water droplets in the steam, air and other gases can affect the accuracy of the flow meter measuring the flow rate. Dry steam coefficient is 0.95, the configuration of the flow measurement error of 2.6%; and boring coefficient is 8.5, the measurement error will reach 8%. Means for supplying steam flow is accurate reliable data to an operator, the production technology for the process control in the best condition and to maximize the production of power, steam and water droplets so that all can not be accurately performed.
Jinzhou construction and installation company needs an electric heating hot water ul certificate standards heat pump boiler house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.
Now condensing gas ul certificate standards heat pump boiler can be divided into commercial gas condensing boilers and industrial gas condensing boilers, mainly for hotels, shopping malls and other commercial establishments and food, chemical, pharmaceutical and other industrial processing industries.
Boilers are classified also by their pressure capacity, design type and use. Maximum allowable working pressure, or MAWP, is the highest amount of pressure that the ul certificate standards heat pump boiler is designed to withstand. This pressure is measured in terms of pounds per square inch or “psi,” and gauge pressure is expressed as “psig.”
