qualified lignite coal hot water wns boiler
Hot water qualified lignite coal hot water wns boiler is the essential equipment of our hotel, one of the parties to provide fast condensing pressure hot water boiler immediate operational effect. Our demand for environmentally friendly and out of the hotel itself, very high environmental performance requirements for boilers, party fast products fully meet our needs, the index after testing are in line with the relevant provisions of the State; with the outside atmospheric pressure remains stable sufficiently improved security index boiler, eliminating our worries. --customer feedback
Details of operation of the qualified lignite coal hot water wns boiler details chemical energy chemical energy Note 1 Note that operation of the boiler, fuel delivery is controlled with respect to the thickness of the layer of coal-fired boilers, the actual operation, the particles of different sizes on the same coal seam, unreasonable distribution, uneven ventilation, combustion is not uniform. The method can be employed uniformly stratified combustion to coal, to improve seam incomplete combustion: first administration of large particles of coal in the lower layer, the upper layer after administration minimal, large particle surface area of small particles of coal, the need to burn a long time, this time is in the air the highest concentration of oxygen lower position; the other hand, small particles of coal on top, large surface area, a low oxygen concentration, full use of excess air. 2, the flow regulating damper excess air ratio is too large, a large loss of smoke; excess air ratio is too small, incomplete combustion loss is large, and therefore need to properly regulate the air flow to minimize loss of two or more. Usually in the flue gas analyzer backpass smoke, the control amount of wind of carbon monoxide is reduced to a reasonable value. For unconditional for gas analysis, empirical judgment by the naked eye can see the flame in the furnace, the flame pale described excess air amount; brown opaque flame, smoke black smoke indicates incomplete combustion. 3, there is a 1mm thick scale surface water quality management experiment boiler heating surface, waste of fuel from about 3% to 5%, in the presence of 3mm thick scale, waste of fuel of about 5% to 10% . Water two general steps: pre-treatment, ion exchange or reverse osmosis. 4, cleaning blowdown gray scale or fouling deposition in the heating surface, increased heat resistance, reduced heat absorption wall, to improve the furnace exit gas temperature, boiler output decreased, but to increase the amount of cast coal, causing furnace exit gas temperature further improve a vicious circle. Therefore, timely cleaning clear dirt is particularly important. 5, the energy efficiency of the heat insulation testing industrial importance boiler showed small boiler in the case of good thermal heat radiation loss is about 3%, if the wrong selection insulation material, the thickness is too small, or even damage, does not include local heat, heat losses will be higher, the boiler has been running, has been caused by waste heat into the air. When the shutdown check whether the furnace wall insulation bricks off; isolated brick flue check is complete, to avoid shorting the flue gas; outer portion boiler, steam pipes and other insulation damage to be repaired; when heat insulation, low thermal conductivity of the material ( i.e., materials with good thermal insulating properties) on the inner layer having a better thermal insulation effect; respond to the economizer outer insulating layer for laying under conditions permitting. 6, to solve the problem of air leakage air leakage boiler boiler unit during operation is a common problem, the need to ensure the tightness of the boiler, furnace air leakage above all, do not close the site to check the furnace wall, door, inspection holes, etc., can be candles law, candles near these places, to observe whether the candle flame inward deflection to judge. Second leakage tail heating surface, the flue stack leakage mostly welding cracks, elbow bend, the expansion joints wear wear; mostly air superheater corrosion or wear leading to leakage through the pipe, the boiler shutdown should focus an examination.
35 tph SZS gas-fired water tube qualified lignite coal hot water wns boiler project for dairy industryPlenty of steam is needed in the milk powder production process of sterilizing, concentrating and drying; therefore, a stable steam boiler has a direct impact on the milk production quality. Heilongjiang Feihe Dairy Industry Co., LTD., established in 1962, has won the Gold Award of Monde Selection. As hazy weather appears frequently in recent years, air quality issues have aroused great concern of the whole society. The Chinese government has successively launched "coal to gas" and other environmental policies to improve the air environment. Feihe Dairy is taking an active part in environmental protection, the company decided to replace the present 2 sets of 35 tph coal-fired steam boilers and one set of 20 tph coal-fired boiler with 3 sets of 35 tph gas-fired steam boilers. Considering that the steam boiler is a core equipment of the production line, the company had attached great importance to this purchase and held an open tender. ZOZEN successfully won the bid with excellent product quality and service, and provided the company with 3 sets of SZS series gas-fired steam boilers. This series of boiler adopts the design of membrane water wall; the gastight test must be done before installing thermal insulation layers, to ensure there is no flue gas leak under the condition of micro-positive pressure combustion and help reduce the heat loss of the boiler body. In addition, to effectively reduce the NOx emission, the boilers are equipped with large volume furnaces and advanced low NOx burners imported from Europe.
How to do when severe water shortages steam qualified lignite coal hot water wns boiler? In the event of a loss in water sometimes makes fireman process steam boiler operation, in the end how to solve it? How do we analyze today with severe water shortages steam boiler? In the operation of the steam boiler process, generally there will be some of the most common failure, the most serious is the boiler water shortages, lack of water is the main cause improper operation fireman, a long time to leave their posts, not the normal water supply. When there is a serious lack of water, do not have an immediate psychological pressure water supply, this is not correct, because the furnace severe water shortages, the various components of horizontal steam boiler is already red, not water supply, must wait until the boiler temperature drop immediately down, square and feed water may access the various components is malfunctioning. The above is how to do when severe water shortages steam boilers and today I will introduce? Content. After nearly a year of research and development company to launch coal, oil, gas steam boiler, the boiler is the biggest feature of this inspection is not required, all operations are automated, and now the case in Anhui, Jilin, Shanxi, Jiangsu and Guangdong have my company's .
