boiler agent steam trap and nrv

Especially after gas steam boiler agent steam trap and nrv tube portions are welded acid corrosion solution, resulting in short-lived gas steam boiler, when washing with an acid solution, suitably added formalin gas steam boiler is controlled by the rate of corrosion by measuring, soil gas steam boiler is above 1.5mm, consider using an acidic solution to clean soil. If the thickness of 0.5-1.5mm dirt, not suitable for cleaning with an acidic solution, consider using novel alkaline detergent or cleaning solution, the cleaning gas steam boiler to make use of a soil removing detergent, dirt small thickness not suitable for cleaning liquid with strong acid.

Central heating hot water boiler agent steam trap and nrvs for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.

How to adjust the boiler agent steam trap and nrv superheated steam temperature reheat steam temperature? 1, to adjust the superheated steam temperature: boiler superheated steam temperature adjustment generally spray desuperheater mainly as a means of fine tuning. Desuperheaters is two or more are arranged to change the amount of water to adjust the size of the high and low temperature steam. Further inclination may be varied and the burner nozzle administered under fire stop, change with the wind conditions and the like to change the center position of the flame as a coarse adjustment means, for the purpose of adjusting the steam temperature. 2, adjust the reheat steam temperature: adjust the reheat steam temperature is substantially recycled flue gas, flue baffle separator, heat exchanger and steam FAW four methods to change the height of the flame center. Using the recirculation fan, the low temperature flue gas economizer section is withdrawn from the vicinity of the cold and then into the furnace hopper, to vary the proportion of the radiation heat absorbing and convection heating surface of the heating surface. For disposed within the convection pass reheater, when the load decreases, reheated steam temperature decreases, the amount of recycled flue gas may be increased, so that in the heat absorption heat increases, maintaining unchanged reheat steam temperature. After the wall with the back pass is divided into two parallel flue, the flue is arranged in two superheater and reheaters, respectively, in parallel with the flue economizer dampers, may be varied adjusting the flow through the plate to open two flue flue gas flow, to adjust the reheat steam temperature. FAW superheated steam heat exchanger is a steam heating to adjust the reheat steam temperature of reheat steam device. For setting the boiler wall and semi reheater radiant reheater can be reheated steam temperature adjusted by changing the height of the center of the furnace flame. Further reheater spray is also provided as an auxiliary micro fine adjustment means.

Excessive moisture content in steam boiler agent steam trap and nrv 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.
