Check Item item hot water boiler hot water boiler comprising a boiler inspection and checking internal use preparations, checking in the furnace and the flue, the boiler attachment check, check automatic control system, the secondary device, check the combustion device, the auxiliary heat check the surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling. It is fed out of the hot water boiler heat equivalent to a mass per hour (usually expressed in tons) in water was heated from 20 ℃ and heat output of all vaporized into a himachal pradesh coal fired steam boiler consumption water absorbed three expressions, in tons) water from 20 ℃ heated and vaporized into all heat absorbed by the steam boiler it is fed out of the hot water heat equivalent to a mass per hour (i.e. typically kcal / hr (kcal / h), tonnes / hour (t / h ), megawatt (MW). (1) kcal / h is in metric units of expression, which represents the heat of hot water boiler fed out per hour. (2) t t borrowed steamed steam boiler popular argument, ( 3) megawatts (MW) is the international system of units unit of power, the basic unit is W (1MW = 106W). this expression formal documents should be used.
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.
6 tons adjusting a combustion gas himachal pradesh coal fired steam boiler consumption, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.
