To ensure the safety of special equipment such as boilers, in normal use, to further promote the comprehensive management of environmental pollution, since April this year, Khorgas Market Supervision Administration of Quality Supervision Bureau for the joint Yili area within the jurisdiction of Khorgas , launched a special safety inspection activities boilers.
Law enforcement officers to be included within the jurisdiction of the major hazard of 12 boiler units of a total of 21 boilers individually conduct a special inspection, focus on examination of the "three implementation, two certified, a test, a plan," the implementation of a detailed view of boiler safety management system, run records.
Test results showed that most of the boiler unit security management more standardized, but there are still some units use boilers run records were incomplete, part of the boiler has to inspection cycle, has been scrapped or dismantled boiler is not write-off and other issues, law enforcement officers to issue on-site boiler sealed, and ordered boiler unit for rectification.
Steam boiler agent 8t steam boiler vietnam price Price: works steam boiler is heated in the drum and water is converted into steam, fire gives off heat in the furnace. Qiang boiler plumbing materials sales center is located in the southern suburbs of Datong City, is a design, sales, installation and service of integrated modern enterprise management. The main environmental operating boiler, a steam boiler fired boiler, a heating furnace, steel radiators, cast iron radiators, canned motor pump, the pump piping, air-conditioning water, galvanized pipe, PP board tanks. Details can be found! Works (in Pulverized example) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (excluding the DC furnace), into the separated saturated steam superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 1, the working principle (as an example in pulverized coal fired boilers) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (except for the DC furnace ), the separated saturated steam enters the superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 2. Pulverized coal boiler operation, the position of the center of the flame will affect evaporation. Generally, low center of the flame will lead to greater evaporation, and the high center of the flame will lead to slow evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Typically, superheated steam, in particular the reheat steam temperature in the lower center of the flame, and vice versa. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined.
Boiler fire phenomenon, how to do 1, furnace pressure fluctuations or to limit and alarm. 2, no flame detector flame, flame flameless television display. 3, flue gas oxygen abnormal fluctuations. 4, steam pressure steam temperature dropped drastically. 5, furnace black, black smoke chimney. 6, the flue gas temperature is reduced. 7, MFT action, turbine trip, splitting the unit. Cause 1, the furnace combustion conditions organizations unreasonable, improper wind coal proportion. 2, the load is too low, unstable combustion conditions without oil combustion vote, or vote, although oil but not good combustion results. 3, cast oil, poor quality oil, oil spray gun is bad, low oil pressure, oil system failure. 4, poor coal quality, coal is too rough, the water is too large pulverized coal combustion adjustment is not timely. 5, the primary air temperature, air pressure is too low. 6, boiler MFT protection action. 7, a large area of the furnace coke collapse, smashing off the flame. 8, severe water wall pipe explosion will blow out the flame. 9, all coal-fired condition, mill pulverizing system failure caused most or all trips. 10, a part of auxiliary machinery such as a fan, blower, fan, air preheater tripped, causing unstable furnace combustion conditions. 11, sootblowing properly, resulting in a large number of normal operation of the furnace ash effects of fire inspection of the boiler. 12, bottom seal damage. Treatment 1, the boiler fire, MFT should be action, otherwise manual MFT. 2, normal inspection device linkage linkage MFT, confirm that all fuel cut. 3. quickly identify the cause, try to eliminate the boiler can be re-ignition, the recovery unit operation. 4, when the mill started again after the trip, the trip must be the primary air tube mill full purge. 5, the MFT operation, checks, Fan normal operation, automatic furnace vent. 6, the MFT movement, check all the secondary purge air damper position is set, the total air volume is automatically adjusted to 30 ~ 40% BMCR sufficiently purged air volume. 7, the MFT operation, when the turbine is in a state disk drive, the disk drive must continue until the normal turbine eccentricity, before re turn red. 8, if temporarily unable to identify or eliminate the cause, restart and could threaten personal safety equipment, non-start. 9, processing according to the corresponding predetermined remaining MFT.
Coal fired watertube boiler is a type of coal fired boiler in which water circulates in tubes heated externally by the fire. Coal fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. ZG Boiler manufactures coal fired firetube boiler and watertube boiler for sales. In Aug 2014, our company exported a set of 15 ton SZL coal fired firetube boiler to Thailand, an paper factory.
