Maintenance pellet burner for hot water boiler hot water boiler is commonly used in the northern winter equipment. In industrial production, gas hot water boiler will be used during the winter heating, and over the winter heating season, the hot water boiler will be idle. In order to ensure the normal operation of the hot water boiler in the coming year, the idle period of maintenance can not relax. First, idle water in the boiler to be drained, ventilated place. Second, the hot water boiler furnace inspected by specialized staff to find cracks repaired, and then apply lubricating furnace or the appearance of anti-corrosion paint if necessary. Third, the disintegration, the different methods used outage duration 1, boiler water drained, draining suction process shutdown 3 days or less before shutdown Ammonia and hydrazine increase dosage, PH value to the feedwater 10 above, and then turn on the water in the furnace at a certain pressure, drained, dried retention system. 2, an amine protecting shutdown deposition method more than three days, a deposition results were better protected amine, such as pure octadecylamine protection, i.e. pure octadecylamine was added to the liquid moisture protection system before shutdown. Fourth, no disintegration, the different methods used in a length of downtime, the pressure holding process gas hot water boiler: outage 10 days or less, ammonia and hydrazine may be increased dosage before shutdown, feedwater pH is increased to the 10, to maintain the boiler pressure. 2, gas protection law: outage of more than 10 days, in the gas phase protection, this method can be long-term protection of the boiler. V. Desiccant method after maintenance outage gas hot water boiler, when the boiler water temperature is reduced to 100 ~ 120 ℃, to discharge all the water in the furnace, use of waste heat, the metal surface and drying the boiler, and the system scale and in all the water clean out slag, and desiccant in a furnace, maintaining the metal surface and dried, to prevent corrosion.
20 tons of gas steam boiler introduce 20 tons of gas boiler can be divided into WNS and SZS natural gas steam boiler steam boiler. Selling models WNS20-1.25-Y (Q), SZS20-1.25-Q, SZS20-1.6-Y (Q). Applications: large-scale central heating, residents of the winter heating gas boiler 20 tons of gas consumption: 20 tons of gas boiler, for example, 20 tons of gas boiler power of 14MW, the heat value of fuel 35.53MJ / Nm3, Zheng pot production of gas calorific value boiler efficiency was between 92% to 90%. Then, 20 tons of gas boiler gas consumption is: 14MW * 3600s / 35.53MJ / Nm3 / 92% = 1541m3 / h. After 1,20 tons of gas steam boiler used for some time: it can be seen from the formula one ton gas-fired boiler air consumption is 1541m3 / h, then, x-ton gas-fired boiler air consumption = x * 80m3 / boiler maintenance considerations can h , when the shutdown of the boiler should let the water out, especially in winter, if you do not turn on the water treatment, it is likely to frozen pipes and storage tanks, shortening the life of the boiler. 2, timely repair or replacement in order to prevent the boiler safety accessory is a security incident, required timing detection boiler safety accessories, such as a safety valve, water gauge, pressure gauge, etc., there is a problem. 3, when a boiler failure, the need for timely shutdown, and notify service personnel of the boiler manufacturer for professional maintenance, use and repair companies must not own, in order to avoid unnecessary losses. 4, boilers are generally mounted with sewage plant, the bottom of the boiler blowdown is very important in preventing flue gas condensation. Meanwhile, in order to prevent the boiler electrochemical corrosion, cathodic protection measures must be taken. 20 tons of gas boiler technical parameters: Furnace: SZS20-1.6-Q desired amount of steam: 20 tons of steam rated steam pressure: 1.6MPa rated steam temperature: 194 deg.] C water temperature: thermal efficiency of 104 ℃: 92% air consumption: 1450 kg applicable fuel: natural gas
State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the boiler from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback
