chemical industry fuel vacuum boiler price
According to instructions, "Neijiang City in 2017 and phase out coal-fired chemical industry fuel vacuum boiler price desulphurization facilities construction program of work", before the end of this year, the city built-up area will be fully phased out in Neijiang City, 10 steam tons / hour of coal-fired boilers and a total of 46 units. Among them, a small city in district out of coal-fired boilers 26, and phase out coal-fired small boilers Dongxing District 15, Neijiang Economic Development Zone small coal-fired boilers out of five. At the same time, accomplish four Chuansha Qi Industrial Co., Ltd. Two 20 tons of steam / hour or more coal-fired boiler desulphurization facilities. A ban on new urban area 20 steam tons / hour of coal-fired boilers, other counties (cities, districts) in principle, the new 10 steam tons / hour of coal-fired boilers. Out of the way including demolition scrap, coal to gas, coal and electricity upgrade boiler swap with large capacity.
We understand that the new Neijiang 20 tons of steam / hour for coal-fired boilers built-up areas, the new 10 steam tons / hour or less fixed asset investment projects in other areas of development and reform, economic and information technology departments will not be approved, approval and filing, environmental protection departments at all levels shall not pass environmental impact assessment, quality supervision departments at all levels do not accept the installation told not arrange supervision and inspection, no special equipment issued registration certificate. Quality supervision departments at all levels cancellation of special equipment for the boiler has been out of use registration certificate to prohibit the production of boiler manufacturers boiler does not meet industrial policy.
Price Price hot water chemical industry fuel vacuum boiler price hot water boiler: gas vacuum hot water boiler use of the characteristics of different water pressure environment of different boiling points. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler operating pressure in the range -0.07Mpa less. Corresponding boiling temperature of water is less than 93 deg.] C, vacuum gas at the operating pressure of the hot water boiler, the combustion temperature rises to the water boiling temperature, the steam boiling surface to produce the same temperature, volatile vapors absorb large amounts of heat. At this time, water is injected into the heat exchanger of the boiler. After the inner tube was heated to an outer cold administered heated steam flows out through the steam pipe outside the cold water cooled heat exchanger is condensed into water droplets, the water cycle is completed in vacuo. 1. smoke tube was added in the process, improve the heat transfer effect of making the arrangement more concentrated. With a square overall structure independent spray, beautiful shape of the separation. three. Large furnace techniques: effectively increasing the heat radiation area of the unit, to reduce the nitrogen oxide emissions. 4. Boiler water using a high water to ensure that water within the boiler fouling and not oxidized. All wet back shell type three-way structure, static heating, excess heat .6, actively control the whole system, it does not require special duty. Seven. Unique pulse level detection circuit having a reliable performance. 8. inlet / outlet temperature display easier to control the operation of the vacuum and hot water boiler operating segment. 9, receiving advanced multilayer insulated glass wool, heat loss is small. Henan fast boiler gas hot water boiler with three vacuum pressure safety system: automatic safety explosion-proof valve in the discharge control: when the internal pressure of the boiler continues to rise, the explosion-proof valve due to EHV broken, releasing the pressure inside the boiler, to ensure safe operation of the boiler; Digital pressure switch: imported from Japan digital pressure switch, detecting a change in the pot at any degree of vacuum, when the pressure is too high, side off: opening vent automatic safety alarm: the boiler when the internal pressure becomes slightly positive, automatic vibration security alarm explosion-proof valve, cutting off the power boiler.
Boiler desulfurization system common faults and solutions (vi) a, filter clogging pressure before the plaster if the circulating pump and discharge pump is too low, the filter is likely to be blocked, the control room will be an alarm signal. In this case, the spare circulation pump must start to alert the circulation pump must be stopped. After stopping operation, process water will automatically clean the filter, the clean, and the circulation pump can be restarted or as a backup. Second, the barrier seal sealing blower fan failure trip operation, the standby seal air fan does not start automatically, report value of the long, come to contact maintenance or fault put into operation as soon as possible. Two seal air fan failure outage and FGD are bypassed, consider a small amount of the original flue gas inlet baffle flue gas leaking into the absorption column, cooling needs, open door water wash demister layer. Third, investment and operation of oil chemical industry fuel vacuum boiler price if the boiler and electrostatic precipitator run oil investment is not in use, report the value of long, to withdraw from the unit flue gas in FGD system operation. Fourth, the ESP fault FGD in operation, such as electrostatic precipitators unilateral have two or more electric fault outage, FGD flue dust export amount is greater than 350mg / Nm3, report the value of long, to withdraw from the flue gas unit run FGD system. V. severe fouling FGD flue inlet and a flue severe fouling bypass flue has a certain influence on the normal switching baffle. When FGD system and boiler outage, check and clean up fouling. Six, SO2 removal efficiency and low processing method, the correction SO2 meter 2, 3 corrected pH meter, if possible, an additional layer 4 runs spray level, check the dose limestone slurry; increase the feed amount of limestone slurry; reaction check limestone 5 performance, the number of the circulation pump and the pump output 6 of the checking operation, the operation start waste water (if not running at this time) 7, inspection of GGH seal air fan and fan seven low leakage, high concentrations of absorber slurry processing method, inspection density swirl number of sub-measuring instrument 2, 3 boiler load reduction, reduced boiler load 4, check outlet pressure and flow, start the standby pump 5, an increase of 6 runs, to check the cast pump discharge pressure and flow outlet 7, the cyclone cleaning gypsum 8, check the concentration measuring instrument 9, the concentration of eight, the vacuum belt conveyor system troubleshooting cyclone underflow (1) Symptom 1, the slurry feed is less than 2, the vacuum seal water flow is less than 3, the offset track belt 4, pump failure 5, a vacuum line system leaks 6, 7 dust concentration is high, breakage 8 with wear, abnormal belt conveyor belt speed (2) processing method, check valve opening to enhance feed 2, check cloth Washing pump 3, the belt deviation control module 4 checks, check the vacuum pump 5, a vacuum line to see whether there are 6 different sound, the control module 7 checks cake thickness, filter cloth tensioning case 8 check, inspection, operation of belt conveyor
