coal firedbiomass pellet steam boiler
Details of operation of the 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.
Oriental Hawaii Holiday Hotel is located in Xiaogan City of Hubei Province in accordance with international five-star hotel standard design, set business rooms, SPA bath, foot care, indoor spa and other facilities in one of the hotel. Hot water boiler is one of the important facilities normal operation can not be separated. With the pace of Hubei Province in response to the national defense of the blue sky, the use of clean fuels gradually increase the proportion of Oriental Hawaii hotel provides visitors to the more perfect leisure experience a sense of the original wishing more polluted coal-fired boilers to replace clean and green gas-fired boiler. After comparing several vendors boiler industry, a number of R & D results very fast square value in the field of clean fuels, entered into a collaboration with the fast boiler. Fast boiler integrally provided a 1.4MW condensing pressure hot water boiler (CWNSL1.4-95 / 70-Y.Q) according to their actual needs. Put into use, fully meet the needs of Oriental Hawaii Holiday Hotel heating and hot water supply.
Gas-fired coal firedbiomass pellet steam boiler, gas steam boiler buy several natural gas boiler should pay attention to, the purchase of natural gas boilers points to note from the National Development and Reform Commission learned that China's coal to gas steam boiler is widespread promotion of the implementation, will enter a stage of comprehensive reform. Xinjiang is about to be the most important work to complete the rectification, the rectification process of the Central Plains and northern regions also increased the intensity and speed of more than 40% of the coal-fired steam boilers, gas-fired completed the replacement of the country. At this stage there are a lot of users need to buy gas-fired boilers to meet the current national environmental policy, I would buy natural gas boiler problems and the majority of users to exchange views in order to buy the rest assured, with satisfaction. First and foremost do with the current coal-fired steam boiler model number and tonnage, boiler gas production and steam pressure that is being used enough, if we can current production, gas production and pressure on the election of equal size gas steam boiler, if not enough or barely enough, you need to choose a slightly larger model of boiler is the second point you are ready or the near future to expand the scale of production, it is necessary to recalculate gas production gas steam boiler, steam boiler of the gas production and future production scale be able to adapt. I met a lot of friends only consider the current, do not consider the needs of the next few years, thinking only meet the current needs on the line, such as the expansion of production and back. The ideas and practices to create a lot of trouble later, the life of a gas steam boiler is probably about 15, you do not have to change a few years, it is only used when processing a lot of losses. Furthermore, the replacement process is very time-consuming, to re-install the application procedures go again, and delayed production. Do not take precautions, you will regret it. The last thing to note is to ensure that the opening of the gas pipeline, if your area has no natural gas pipeline, is to buy a gas steam boiler also spend the. In determining the purchase of gas-fired, the first not to rush to the boiler transported to the site, first opened gas pipeline things well. A client told me: "I opened a mouth, a natural gas company gave me to do 100,000 a month just to run." So, first hit the point about the relationship, try to spend less money to natural gas mouth opened, then natural gas boiler shipped home.
What is its auxiliary boiler feedwater oxygen has several categories? Boiler, I believe we are not unfamiliar with and understand it, if you have been concerned about the site and read the relevant article and master the relevant knowledge and content words, so below, it may be in front of the existing foundation, to continue the products of study and work, so that we can make progress in their learning and development road, and at the same time, you can also reach the intended target as quickly as possible. 1. ship boilers and boiler land, they are the same? Can GM? Marine boiler, which is used to generate steam, or fuel for heating domestic water, and may also be in the kitchen in the ship. However, it is compared with a land boiler, there is a big difference, such as shape and size. So, they are not identical, nor is it universal. 2. auxiliary boilers, there are a few main categories? Auxiliary boilers, which can be divided into six categories, the specific terms, it is the coal slag or counseling classes, containers, water treatment class, class fans, smoke and dust classes and appliances category. Wherein an expansion device containers, and other such sub-cylinder, the fan type blower and is mainly induced draft fan. The appliances, mainly for electric and control these two aspects.
