How to prevent gas 1 ton fired hot water boiler explosion gas hot water boiler belongs to the category of special equipment, thermal equipment and is a frequently in high pressure high temperature state, it is inevitable some small problems that may occur during operation, this is normal; but if not in place or because of negligence, they are likely to make the boiler exploded. So, for safety equipment and personal safety, we have to understand some common sense prevention hot water boiler explosion. 1, hot water boiler furnace explosion prevention occurs first on the boiler design, should be strictly thermodynamic calculation and strength calculation in accordance with the requirements of GB50041-1992 "boiler room design specifications", the structural arrangement should be reasonable, material quality should meet the requirements. Boiler manufacturing, construction plans should ensure compliance with national quality boiler scale delineation. Boiler safety accessories should be complete, agile and reliable, and maintenance schedule, often check on the failure of the attachment timely replacement. Schedule for maintenance of the boiler, the outer part of the boiler maintenance, subject to the existence of timely repairs and reconstruction to ensure test quality standards. 2, prevention of fuel, gas hot water boiler furnace explosion at the point of blast furnace to double-check each gas line, oil line is tight (leak), pressure is normal, Installation and reconstruction of new oil and gas pipelines necessary to purge and clean. Check the ignition lead before the drum whether the fan has to take the air 5 ~ 10min, after ignition failure to analyze the reasons, and then restart the ignition process to take the air ignition. Boiler use permit and inspection certificate did not apply for the boiler, furnace stokers right to refuse point. Enterprises should choose a fireman permit manipulation of experienced fireman point-furnace work, fireman staff should strengthen the inspection tour, identify problems in time to prevent the flame; flame once found, should immediately cut off fuel. Boiler installation should be controlled protection device, comprising an automatic ignition, flame protection, automatic adjustment of combustion and the necessary alarm chain protection.
Since "strong piece autumn and winter air pollution in a comprehensive way, determined to win the Battle of Hebei blue sky" press conference was informed, Hebei Province, to make arrangements for winning the Battle of the blue sky, requested the preparation of implementation of the blue Battle Hebei Province Government Information Office held three-year operational plan and cleaning winter heating three-year plan to ensure that changes every year, three years, a large bear fruit.
Really good job of air pollution prevention and control work in the past year, Hebei Province, adhere to the scientific governance haze, collaborative governance haze, haze iron-fisted rule, will coordinate development of pressure energy, reduce coal, running enterprises, dust, vehicle control, by Green et key tasks, play a set of tackling the problem, the main root of the problem "combination punches." Where the complete substitution of gas for coal, electricity-generation coal transformation 2,537,000, Yajian steel production capacity of 27.54 million tons, 21.32 million tons of iron, coke 8.088 million tons, 10.68 million tons of coal, Reconstructing "scattered dirt" Enterprise 38785, off stop banned enterprises 68747, the new afforestation area of 741 hectares. At the same time, also launched a special inspection of law enforcement inspectors and four comprehensive management of air pollution, to carry out unannounced visits to check the dark, spot checks, cross-law enforcement, road law enforcement to crack down on environmental violations, and earnestly solve the "last kilometer" problem.
Director, Office of Atmospheric Hebei Province, the provincial Environmental Protection Bureau Director Gao Jianmin, said: "This year we will develop science of air pollution control 3-year operational plan, a clear timetable, route map, to promote the key cities 'insurance bottom line, back ten' focus on tackling to ensure that air quality 'changes every year, three large effective', and strive to Shijiazhuang, Hengshui, Tangshan City, the first exit after ten. we will actually improve air quality and enhance, to better respond to the concerns of the masses, improve people's livelihood well-being, and enhance people's sense of well-being obtained. "
Further, the sulfur content of natural gas is also very small, and the coal-fired boiler dust removal, desulfurization, denitrification had on the gas boiler need only consider the problem of denitrification. 3, from the point of view of other waste emissions, natural gas, almost no other pollutants, especially in urban gas; and coal, then coal field (especially small boiler mostly built on open air) during the rainy season will produce slime water into groundwater import or surface water, after burning ash transport will produce dust. 4, of course, there are differences from other areas, for small boilers for gas-fired boiler energy efficiency is higher than a lot of coal-fired boilers, process equipment is simple, small footprint, low cost of operation and maintenance and so on.
10 t 10 t introduce gas boiler gas boiler steam boiler dedicated configuration computer controller, all Chinese, a large screen, backlit LCD display strong, rich display, operating status of the controller and the collected pressure, water and other states may be accurately visually displayed. Complete control functions, with intelligent boiler water level control, steam pressure control, low-limit water level alarm and interlock protection, high water level alarm, ultra-high pressure steam alarm and interlock protection, automatic control functions. Very convenient to use, may be provided continuously, the timing of the two states, the timing can be divided into four time periods, the boiler regular boot, time off, without full fireman, usually only have to press the start key turned on, press the stop button to stop very easy. Features: imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) to automatically adjust the proportion of oil wind, good atomization, combustion, low NOX, energy saving . Under normal circumstances, when the boiler steam pressure reaches the set value, the burner combustion is automatically stopped, when the steam pressure is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically. Advantages 1,10 tons of gas steam boiler furnace design and manufacture Three-pass boiler, wet back, eccentric furnace, asymmetric structures, waveform furnace, so that the flame produced a strong disturbance, and increased radiation heating surface, increased strength heat transfer coefficient, and can effectively prevent metal thermal expansion and contraction resulting in reduced life of the device. 2, the whole high degree of automation, security improved. Run fully automated process, with automatic replenishment, water shortage, overpressure, automatic power off and alarm, leakage protection and other security systems. 3, the whole body as glass wool type insulation, light weight, good thermal insulation effect, less heat loss; protection system: (1) protect the boiler water level indicator and integrated design of the boiler, the appearance of a more compact appearance, function accurately display the boiler The actual body of water. Coupled with dual independent electronic water level control system to achieve ultra-low water level in the boiler, low water level automatic adjustment function, the normal water level, high water level, ensure that the boiler in a variety of unforeseen circumstances foolproof, secure home. (2) steam pressure protection ☆ pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switch, other control lines or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; the pressure controller may be single or double fire burning fire the actual operating pressure regulator. ☆ safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.Free Chat
