high pressure oil fired water tube steam boiler

Central heating hot water boilers for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.

The scaling of gas-fired high pressure fired water tube steam boiler not only reduces the thermal efficiency of the boiler, but also increases the temperature of the heating surface of the boiler, causes damage to the heating surface, and even causes the explosion accident of the boiler. Therefore, the use of soft water treatment equipment, strictly according to the process operation of boiler feed water softening treatment equipment, control boiler feed water quality, can delay the formation of the scale. At the same time, it is very important to control the boiler scale in real time, master the boiler scale and clean the scale if necessary. Because the temperature of the gas-steam boiler body and the steam-water heat pipe system is higher than the air temperature in the boiler room, some of the heat is emitted through radiation and convection into the surrounding air. This becomes a loss of heat. Boiler Therefore, the heat loss should be reduced when the heat insulation and heat pipe system of the boiler are damaged or leakage is discovered. The increase in noise from gas-fired steam boiler burners is mainly due to the closure of the valve or insufficient oil intake in the oil path, blockage of the oil filter, or because of low inlet temperature, high viscosity or oil on the pump. Too high temperature; oil pump failure; fan motor bearing damage; due to dirty turbine impeller, the equipment is too loud. This failure occurs when a gas-fired boiler is in use and is not easy to atomize (heavy oil) because of the high viscosity of the oil; it is also due to cyclone and jet The distance between the nozzles is inappropriate; in addition, because the burner is worn or dirty; it is also due to the excessive heating temperature of the spare fuel tank, resulting in steam pumping the oil pump out of the oil pump; or because the oil in the oil boiler is hydrated. Gas steam boiler feed water contains a variety of impurities and calcium, magnesium and other scaling substances, the boiler will inevitably expand. The thermal conductivity of the scale is very low, so once the surface is polluted by the hot surface, the exhaust temperature of the boiler will increase, and the heat loss of the exhaust gas will increase due to the increase of the thermal resistance. The experimental data show that the heat loss of waste gas will be increased by about 2%-4% when 1mm oxide is formed on the heating surface of boiler. The thicker the scale on the heating surface of the boiler, the greater the thermal resistance, and the lower the thermal efficiency of the boiler.

Henan daily operation of the gas boiler 1. Contact chemical maintenance, turbine attendant prepare enough desalinated water, oxygen, water passing temperature no higher than the drum wall temperature 50 ℃; Sheung during hot drum wall temperature should be , metal temperature is not more than 40 ℃. 2. After the new installation or repair before Henan Gas Boiler Feed recorded once ministries indicate expansion. 3. Sheung summer time less than 2 hours, at least 4 hours in winter, when the temperature and Sheung drum wall temperature difference of less than 40 ℃ 4. How Henan gas reheater boiler corrosion protection? (1) turbine playing gate , to ensure that a boiler blower, preferably a cross ID fan, two reserved oil gun. (2) open to the air reheater exhaust steam reheater hydrophobic air door and the door be preserved, to be preserved reheater predetermined temperature below 400 deg.] C for steam. (3) controlling the drum water level within an allowable range. (4) to ensure that the chamber negative pressure 50--100Pa, each of the flaps open, baffle for ventilation less than 5 minutes, stop sending, Fan, each of the flaps closed tailgate may be appropriate to accelerate Sheung speed.

10 tons of gas turbine high pressure fired water tube steam boiler burner it currently requires 10 tons of steam gas boiler steam boiler there are two types WNS10-1.25-Q SZS10-1.25-Q, and two kinds, i.e., three horizontal wet return back structure and vertical type double drum "D" type arrangement quick water tube boiler. It consists of upper and lower drum, membrane wall, superheater, economizer and convection bank composition, the burner disposed on the front wall, the fuel combustion in the furnace, the flue gas through the first convection bank, superheater, a second convection economizer tubes and into the chimney. 10 tons of gas boiler burners have split and one-piece points, integrated burner fan I see are axial fans, centrifugal fans with split, 90% of the 10 tons of gas boiler burner all-in-one, as to form two burner what a good way, this has yet to be explored. SZS10-1.25-Q has the following features in gas boiler: The product has the following characteristics: ⑴ This double boiler drum "D" type arrangement, a compact, small footprint, good flame fullness. ⑵ boiler lower support mode can be free to expand upwards. ⑶ using membrane wall furnace wall structure which reduces maintenance work and use of refractory bricks. This boiler ⑷ fender an airtight closed welded structure, good sealing furnace wall; outer layer of pressed boards, appearance, beautiful. ⑸ this boiler furnace inspection hole is provided for the use, maintenance provides a great convenience. Roof has explosion-proof doors. This quick ⑹ boiler structure can effectively shorten the installation cycle. ⑺ high thermal resistance material as a heat insulating layer, good insulation properties. ⑻ economizer arranged tail, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler. ⑼ whole boiler steel holder on a strong base, convenient installation and transportation. ⑽ boiler heating surface has a surplus, soft drinks and large enough space to ensure the stability of the boiler parameters. ⑾ using automatic burner, combustion efficiency and an ignition control program and overpressure, flame protection. ⑿ continuous electrically adjustable water supply, and having a low water level alarm, the protection function chain. ⒀ using spray desuperheater, sensitive temperature adjustment, temperature control large amplitude. Second, the structure Introduction boiler 1, the main evaporation rated specifications: D = 10t / h of superheated steam temperature: t = 300 ℃ superheated steam pressure: P = 1.25MPa water temperature: tgs = 20 ℃ (except normal saline) boiler efficiency: η = 92.6% exhaust temperature: tpy = 136.3 ℃ desuperheater tYPE: hydrostatic pressure test boiler desuperheater spray: 1.75 MPa number of valve: drum 2 PN2.5, DN80 full open spring valve overheating an outlet header PN2.5, DN50 full open spring valve design of the fuel: 0 light diesel oil (Qydw = 41870kJ / kg); consumption 749.9kg / h of natural gas (Qydw = 37060kJ / Nm3); 847.3 consumption Nm3 / h
