Steam boiler When should an emergency shutdown when the steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.
Check Item item how much is a 1-ton coal 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 steam boiler 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.
Gas how much is a 1-ton coal hot water boiler and coal-fired hot water boiler What is the difference? Boiler There are many different types of coal-fired hot water boiler is called coal-fired boilers, which burn gas is called the gas hot water boiler. Well, apart from the name calling is not the same, not the same fuel used in addition to, what difference there is between the gas hot water boiler and coal-fired boilers do? Here versatile efficient and practical to introduce the gas hot water boiler manufacturers. 1, there is the environmental impact of the difference we all know that coal burning when smoke will emerge, these scattered black smoke into the air pollution on the environment which, therefore, coal-fired coal-fired hot water boiler in the use of the process there will be a lot of black smoke, the environment can also cause a very bad influence. However, the gas hot water boiler gas, combustion gas is sufficiently, so use will not have a smoke discharge, wherein gas containing not cause damage to the environment. 2, heat loss generated by coal-fired boilers are different often requires manual or auxiliary equipment will be added continuously to burn coal to the furnace, when the pressure of the fire will cause greater heat loss, if the manufacturer is intermittent when the coal-fired hot water boiler starts up again, the furnace temperature you want to raise to the desired temperature will take a long time. However, the gas hot water boiler can quickly increase the temperature of the furnace, so as to reduce the loss generated when the batch operation. 3, the post-combustion treatment there is a solid body difference coal, coal ash will be generated after combustion, coal ash can not be disposable, it is necessary to transport it to a special slag field. Gas hot water boiler is a gas, the gas is not generated in the combustion of solid waste, and therefore no need to do special processing after the combustion. Thus, coal-fired and gas-fired hot water boiler hot water boiler, although only one word, but a huge difference, and that's obvious, gas hot water boiler has the advantage of more aspects than coal-fired hot water boiler, Therefore, the company could do some good gas hot water boiler which brand, sourcing high quality and reliable gas hot water boiler to use.
