Steam boiler rules Henan fast boiler with small series to introduce the company's 3ton fired steam boiler operating procedures. First, the components of the steam boiler before oven cooking oven and check (a) and oven cooked boiler furnace must be checked in detail. Check the following items: 1, cold chain grate test more than 24 hours, cold test should meet the following requirements: (1) grate should be smooth turning chain wheel axle, found arched, two tension bolts can be tightened. (2) the active grate sprocket good occlusion. Minimum gap (3) on both sides of the active grate block with the side seal and the side seal angle not less than 6 mm. Distance (4) on both sides of both ends of the furnace grate platoon leader pin in the sprocket should be kept equal. If it is found at one end to the occurrence of side friction, long waist-hole may be a tap with a hammer, the end surfaces on both sides remains equal distance. (5) steam boiler grate rotated without jamming, deviation phenomenon, when the deviation found by the inspection hole into the rear grate tail, the tie bolt align the two bearings of the drum, deviation phenomenon can be eliminated. The boiler has ignition combustion, still need to transfer found Hearth n, just before two adjustable chain tensioning bolt shaft directly outside the furnace, but preceded align the front sprocket shaft and a gearbox connect the safety pin or bolt removed until after squaring shaft to a gearbox with a chain alignment pin or bolt after tightening, may otherwise result in misalignment with the sprocket shaft of a gearbox and mechanical damage. (B) Check broken grate furnace platoon leader pin is bent, if long waist hole in the furnace may be carried out at any time platoon leader pin alignment reload. (C) a chain grate does not allow foreign matters (such as bolts, nuts, nails and other iron) is present. (D) firing door open and flexible, easy to open and drop the shutter coal, coal gate left and right side of the grate surface distance equal to, the thickness of both sides of the seam to ensure equal furnace, as a method for reducing ranging from links available to make equal, coal shutter cover plate should cover tightly to prevent leakage into the coal, coal stuck shutter. (Five) of each grate windshield of smoke damper and damper adjustment inside the flue flexible switch. (Vi) blower, Fan, Java machine, commissioning normal water supply equipment. (Vii) manhole, hand hole is tight, attached parts fitted Ge are complete. (Viii) the furnace wall is normal, the flue is tight. (Ix) steam boiler pipes, water pipes, sewage road is complete. (J) all filled with lubricating oil in the bearing housing and oil cup. (Xi) All electrical equipment should be empty running test, inspection equipment, and other electrical lines is intact.
There are many types of steam oil-fired boilers followed by the main uses, main features, a brief introduction to the automatic oil-fired gas-fired steam boilers.1: main uses: fully automatic fuel-fired gas-fired steam boilers provide production steam for food processing, printing and dyeing, pharmaceutical production, disinfection steam for medical institutions, and steam for heating of other enterprises and guesthouses. Domestic hot water can also be provided by water tank heating. Two: main characteristics: 1, adopt the central reburning structure, boiler water volume and gas space is large, adaptive load ability is strong. 2. The flame is burned under micro-positive pressure in the fully automatic steam oil-fired boiler, the flame extends completely, and the heat transfer is enhanced, thus the convection heating area is reduced and the boiler cost is reduced. The flow resistance of flue gas is small and the power consumption is low, so the operation cost can be saved. 3, in addition to the traditional four water level height control, add the fifth water level detection, the boiler will stop when the water shortage occurs, alarm, ensure the safety of boiler operation.
How to deal with water shortage in electric 3ton fired steam boiler machine in use for some time this or that problem will be serious delays in the progress of work, causing great inconvenience to the people, such as water shortage, this problem arises in the use of electric steam boilers after a period of water shortage in how people deal with how to solve it. Electric steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.
In the near future, at home and abroad more than hazardous chemicals, major accidents have occurred, causing casualties and property losses. Is a profound lesson, Henan Energy Regulatory Office will co-Provincial Development and Reform Commission issued the "Notice on alternative transformation of the province's coal-fired power business major hazard (liquid ammonia tank)" and actively promote the province's power industry ammonia tank alternative transformation.
"National Development and Reform Commission and the National Energy Board to implement the views on the promotion of electricity reform and development of the field of safety of" clearly "to strengthen the major hazards source control, there are significant hazards during the production of coal-fired power generation enterprises should study the implementation of major hazards alternative rehabilitation programs. " Henan Province TV as fire, liquid ammonia tank safety risk management and control situation is grim. To actively implement the "opinions" requirements, Henan Energy Regulatory Office investigation and carefully combing the province's power industry the basic situation of major hazards, and actively carry out reconstruction work research initiative to communicate the situation with the Office of the Provincial Development and Reform Commission, the provincial emergency management, efforts to promote reconstruction work as soon as possible. "Notice" requirement province of the power generation enterprises should further enhance political stance, overcome difficulties, vigorously promote the major hazard (liquid ammonia tank) and Improvement, under the premise to ensure safe production, the province's coal-fired generating units and strive to 2020 in liquid ammonia tank renovation completed before the end of December. New coal-fired power generation projects should all use the technical route no major hazard.
Next, Henan Energy Regulatory Office will replace liquid ammonia around the transformation as an important safety regulation. For failure to complete the transformation of liquid ammonia replacement power companies, to be included in the list of key regulatory target, for there are significant risks or accidents in accordance with regulations to be strictly punished according to law, and urge enterprises to strictly implement the main responsibility to effectively prevent accidents, efforts to increase intrinsic safety level of the enterprise.Free Chat
