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 ℃.

What are the reasons gas steam boiler popular? What is the reason gas steam boiler is popular? 1: the use of more environmentally friendly cleaning gas steam boiler. Gas new sale hot water boiler in tashkent with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing users enjoy the reputation as the cost of natural gas is a clean fuel, do not emit harmful gases and soot in the combustion process. Therefore, do not pollute the air and the environment. Soot or carbon dioxide generated by conventional coal-fired boilers not only affect the air quality, but affect the health. Therefore, the use of gas steam boilers are environmental requirements. 2: high thermal efficiency of the reaction gas used in the thermal efficiency of the steam boiler is faster than the reaction of other aspects of the boiler, because natural, natural gas is used as a pollution-free high heat of combustion of the fuel, the higher the fire, heat faster switching speed, steam from the water pot and continue to release the faster. Compared with other coal-fired and oil-fired boilers, thermal efficiency is the fastest, most effective. Third: run more intelligent gas steam boiler does not require manual operation, does not require complex operational intelligence Zidongkongzhi whole process. All the work process only requires prior set all the parameters you can use. Gas steam boiler design according to user requirements, start, stop, automatically adjust the water supply load. Occur during operation of any abnormalities can also achieve self-diagnostics, interrupts combustion, sound and light alarm.
March 22 to 23, Ganzhou City, Jiangxi Province Bureau of Quality Supervision established party leadership team, the progress of the 2018 phase-out of coal-fired boilers to conduct random work. Leading group led by Liu Ping, deputy director of Ganzhou City, Municipal Quality Supervision Bureau, the Municipal Industry and Information Commission, the Municipal Environmental Protection Bureau and the Municipal Development and Reform Commission composed of four departments jointly checks group within Xinfeng County of Ganzhou City, Nankang District, Jiangxi counties and carried out spot checks Yudu County coal-fired boilers working-out of a total of 17 companies.
Sampling results show that 17 companies, more than 10 companies to complete phase-out of coal-fired boilers, the other seven unfinished business executives also said that this year will be to complete the rectification work before December 20.
In this sampling event, checks the group also proposed rectification direction of the coal-fired boilers for local authorities: by strengthening the policy advocacy, strengthening inter-site inspectors guidance and strengthen departmental interaction, the three parties work together to ensure the timely completion of this non-compliance within Ganzhou coal-fired boiler out of the task.
What impact have fuel moisture steam boiler? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.
