Henan local structure vacuum fired vacuum boiler furnace fast vacuum hot water boiler is divided into two portions, wherein the lower half of a structure similar to the second and third boiler shell flyback steam boiler, i.e. heating surface and furnace flue thereof; and the top portion a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating circulating water flowing through the heat exchanger. The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in a closed body of "boiling evaporation == == == heat medium condensed water" cycle, so no condensation water supplement, dry and no danger. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest.
In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired fired vacuum boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
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 fired vacuum boiler 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
