electric steam boiler for food industrial
How to prevent running back pass secondary combustion 1, 30% of the rated boiler to deal with the amount of purge air before boiler ignition; the boiler must be 30% of rated air flow purge less than 5 minutes after the boiler fire, or allowed to boiler re-ignition. 2, fine-tuning the boiler and combustion systems pulverizing system operating conditions, to prevent incomplete combustion of oil and coal accumulating on the tail heating surface or flue. 3, boiler burning oil, adjust the proper air flow, fuel flow, confirming good gun oil spray, burning completely. If you find a bad oil spray gun should be discontinued immediately, and clean up. 4, when the oil application group administered powder, cast powder should be confirmed before the oil burner ignition good, or allowed to cast powder. 5, the oil powder boiler during cofiring, and check the fuel oil gun system of fire reinforcement. 6, normal operation, operation personnel in monitoring the economizer, an air preheater flue tobacco in different conditions of temperature, abnormal, should be checked to detect a fire-place. 7, air preheater sootblowing steam system normally put into operation, the soot-blowing pressure and temperature in a predetermined range. When the unit load or less prolonged 300MW kerosene mixed combustion, air preheater sootblowing steam to be continuous. 8, the air preheater into a reliable fire alarm device. 9, an air preheater inlet and outlet fume / air damper, and should be able to put an electric shutter can be open, closed tight. 10, if found preheater stall, should be put into operation again immediately, if not turn back, they should be isolated.
About Code of Practice Code of Practice for the safe operation of the hot water boiler hot water boiler hot water boiler safe operation because of its specificity required safety practices. Understandable that the normal life and production are inseparable from the use of the hot water boiler. How hot water boiler safety issues need to be protected? 1, carefully check the work before the hot water boiler, drainage, gas pipe fittings, safety valve, pressure gauge, water level, is sensitive so that, after confirming it is safe to operate. 2, with both hands to manipulate when Sheung hand to open the door of water, whereupon the other hand the water injector and valve open, the water naturally into the furnace. When stopped, the steam valve should be closed first, then turn off the water door, switch and valve, the front face must escape to avoid soft drinks out of the accident. 3, hot water boiler in operation, inspection departments to pay attention to observe the pressure and water level. Fireman are not allowed to leave their posts without permission, when night work, avoid dozing off, more sleep deprivation, in order to avoid accidents. Hot water boiler blowdown, must be performed once per shift, adjust the water level in the sewage before, slightly higher 2/3, followed by sewage. 4, the water level table class must be flushed once. When flushing, according to established procedures, the first closure valve and open the drain valve, flush valve steam, steam at this time pay attention to the origin is blocked. Steam valve is then closed, when attention is blocked antecedents water. Flushing valve, until the water becomes steam, some a little longer, in order to guarantee no false water level. Hot water boiler coal must be checked, to prevent coal detonator explosives and other explosives thrown into the furnace, to prevent the risk of explosion. 5, to always check the temperature of the motor housing and the machinery, such as mechanical failure or an electric motor with a fever more than 60 degrees, stop testing immediately. Hot water boiler normal operation, the vapor pressure shall not exceed the operating pressure, the safety valve inspection once a week.
What is different from the hot water boiler and steam boiler there? There are many companies will operate on steam boilers do this relatively high cost of care. After the scene since the late boiler equipment, equipment up and running is a big sum of costs. About enterprise, if choose for their own fuel boilers, boiler fuel efficiency will make use of further progress. Therefore, we demand that the cost of running on several different fuel steam boilers budget to know. Gas: Advantages: clean energy, high thermal efficiency, low cost. Disadvantages: gas adapter constrained condition. Produce one ton of steam costs about 240 yuan (gas prices by 3 yuan / square meter accounting). Fuel: Advantages: no pollution, high efficiency, no fuel constraints. Disadvantages: higher operating costs. About 594 yuan one ton of steam production costs (fuel prices accounted for 9.0 yuan / kg). Electric heating: advantages: no pollution and no fuel constraints. Disadvantages: is a secondary energy, high operating costs, the cost of producing one ton of steam is about 700 yuan (price 1 yuan / degree). Coal: Characteristics: low operating costs. Disadvantages: severe pollution in some areas, the use of restraints, cost of production of one ton of steam is about 150 yuan (coal prices by 1,000 yuan / ton accounting). Heat boiler is an important means to transfer heat to the appropriate fuel equipment, it is now being widely used in industrial production and heating and so on. Popular in the size of the boiler is a steam boiler and hot water boiler both types, many people who only know the boiler heating equipment, but can not tell in detail parting boiler. Today we gave Shandong steam boiler explain what the differences steam boilers and hot water boilers, after all, what! On the surface, we can understand heating hot water boilers and steam boiler heating method chosen is not the same, but the distance between the hot water boiler and steam boiler Moreover, detailed in what areas? The different output media we literally can be seen, the medium is hot water output from the boiler, medium boiler steam output of the steam. First, the user can according to their demand for the output media, choose the appropriate boiler. Different steam boiler space occupied by a high pressure vessel, through steam forming water is heated after the completion of the vapor compression heating, and the area of the pressure vessel by the use of less water boiler is an unpressurized vessel by virtue of heat temperature of the water to complete the heating, hot water boilers professional usually occupied by a larger location, but better able to complete the non-selection of the pressure vessel safety are better able to ensure the safety of those who use. Because the size of different heating and heat storage capacity of water vapor from a large, high-volume hot water boiler and thus be able to choose long-distance transport of heat pump delivery lost less able to complete large-scale transport of hot water requirements. The steam boiler because the steam freezes faster, so in the long-distance transport can lead to sudden drop in water temperature, so the size of two kinds of heat supply boiler equipment can withstand different. Heating steam boiler at different speeds when using the heat generated as the water transpiration and thus burn calories in order to ensure the needs of large steam generation, and thus the temperature rise faster fever faster speed; hot water boiler heated water to ensure that the temperature of the water in the use of Yung heat better, thus better able to maintain the heating heat.
During the training, the participants visited the group to arrange a call center, research and development centers, production workshop, the participants said that through this training visit, the other fast Group's corporate culture, lean management, staff professionalism with a deeper understanding of each other soon Group Technology R & D investment, product quality control, after-sales service system construction with understanding. Participants said that the current visit and study, the other group soon have a new understanding, and trust each other more products faster, this is very good training visits, Hope Group to adhere to gone out of existence. Safety Training Week is running fast party group of service users yet another form, the Group will integrate a variety of services in the form of online and offline, adhere to convenient and efficient service concept, to provide users with the best quality service.
