Category Description oil-fired boiler fuel gas-fired boiler is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. If the hydrocarbon injected into the furnace with the air mixing within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a chassis, the assembly may also be medium-sized factory. Boiling water boiler fuel oil boiler fuel, also known as water heaters, stove oil, furnace fuel tea, water boiler fuel, is living in a boiler, belong to the category of civilian atmospheric boiler. The boiler is a fuel oil as fuel by a burner to heat the water, when the water temperature reaches the set temperature (water), the burner stops working, heat boiler into the automatic state, the user starts to provide water, oil and water if the boiler holding tanks connected to meet like hospitals, schools and other centralized water supply demand type units. Hot water boiler fuel oil bath center hot water boiler seller in hoi an fuel refers to fuel have mainly boiler fuel hot water boiler with a high-tech automatic control system, with a number of security devices, water protection, overpressure protection, flame protection abnormal pressure protection, over-temperature protection flue; using high-tech structures, having a body holding a small, compact and easy to install, simple operation, automatic adjustment, the pressurized fuel to the atomizer, and then allowed a slight positive pressure fuel combustion burner more fully, to reduce the loss of gas emissions and fuel, it is a modern industrial steam to use the most convenient and most energy-efficient, environmentally friendly standard products. Fuel steam boiler fuel (gas) steam boiler, a horizontal combustion all wet back, efficient threaded pipe, with a sound insulation outsourcing design, the boiler thermal efficiency as high as 85% or more, product design, rational structure, process performance is good, so that this product has extraordinary excellent quality.
Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of boiler welds is more guaranteed.
The 1 ton wns series oil and gas boiler adopts a horizontal three-return structure, and the boiler produces fast steam and high thermal efficiency. The boiler adopts a large-area combustion chamber. The combustion chamber is surrounded by a jacketed water jacket. A dense fire tube is arranged on the upper part of the combustion chamber, and an advanced combustion device is arranged. The fuel is fully burned in the combustion chamber, and the high-temperature flue gas enters the dense fire tube to continue to radiate heat. Then gathered in the smoke chamber for further heat release.
Pressure fire operations and precautions Henan fast boiler's steam boiler 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 ℃. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
