Wns Series Horizontal Oil Steam Boiler for Factory

Principles of wns series horizontal steam boiler for factorys and solutions hydraulic external gear: told you about the principles of steam boilers and solutions for steam boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil steam boiler, gas steam boiler three kinds; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, a large steam boiler plurality of three-pass horizontal structure. If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories.

It is understood, Shaanxi Province, 2018 - Continuing to promote the 2019 inspection work in key areas of defense sky war, now in its third phase. November 22, according to the requirements of the program of work for the inspection team to carry out all the Guanzhong area of ​​Shaanxi Province counties (cities, districts) inspection work, inspected 262 units, identify problems and 49, have been transferred to the supervision of Shaanxi Province 20 .

20 environmental issues in the supervision, accounting for 8 in Xi'an, Weinan City, accounting for 7, Baoji City accounted for two, accounting for two Xianyang City, a Korean city of Tongchuan City, Yangling Demonstration Zone and the New West Ham is not problem found.

More units found the problem, companies of "scattered dirt," the one, accounting for 5%; industrial pollution prevention and control 10, accounting for 50%; a coal-fired boiler renovation, accounting for 5%; comprehensive management of dust 1 , accounting for 5%; complaints 4, accounting for 20%; at three open burning control, accounting for 15%.

Steam boiler rules Henan fast boiler with small series to introduce the company's wns series horizontal steam boiler for factory 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.

Pressure fire operations and precautions Henan fast boiler's wns series horizontal steam boiler for factory Xiao Bian told you about the operation of steam boilers and pressure fire precautions and stainless steel high temperature magnetic pump structural characteristics 1. pressure steam boiler fire steps of (1) to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. (2) to the slag is thickened seam about 1 mm from the stop grate rotation, the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal the lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the coal-fired back, a distance. (3) the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, can be restored run. 2. Note the use of a steam boiler (1) before starting Check power supply voltage, there are unusual circumstances water, close the drain valve opens the water supply valve, check whether the pump stuck, stuck if the pump, remove the fan cover, rotation of the motor shaft to the flexible state to boot. (2) When the steam boiler maintenance or replacement of parts, turn off the power to avoid live work dangerous. (3) electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean. (4) steam boilers in accordance with quality requirements, when using the apparatus sure to install a water softener, the water softener is not used because the boiler may cause fouling, may cause serious squib, shortening the life of the boiler. (5) Please note that when using sewage. And at least once a day with a discharge pressure of between 0.1MPa to 0.15MPa discharge may be prevented clogging of pipes, sewage should be properly connected, to guard against burns. Stainless steel high temperature magnetic pump structural features: a sliding bearing magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. Because of engineering ceramics has good heat resistance, corrosion resistance, abrasion performance, so the sliding bearing magnetic pump more use of engineering ceramics production. Because of engineering ceramics are brittle and expansion coefficient, so the bearing clearance is not too small, so as not to hold the shaft accident. Since the magnetic pump in order to lubricate sliding bearing medium conveyed, it should be used depending on the medium and conditions, making use of different materials bearing. 2. Cooling lubricating fluid flow control pump operation must be flush cooling internal friction annulus region between the sliding bearing and the magnetic rotor and the containment shell with a small amount of liquid. Coolant flow rate is typically 2-3% of the design flow of the pump, the annulus area between the inner magnetic rotor of the eddy current generated spacer bush high heat. When enough cooling lubricant or flushing holes poor, clogging, the medium will result in a temperature above the operating temperature of the permanent magnet, the inner magnetic rotor gradually loses its magnetism, the magnetic force actuator failure. When the medium is water or water-based liquid, the temperature rise can be maintained in the annulus region of 3-5 deg.] C; or when the medium is a hydrocarbon oil, allows the annulus region of the temperature was maintained at 5-8 ℃.
