oil fired vacuum hot water boiler in ireland
The only example of an ultra-low nitrogen oxide emissions through boilers Enterprise Test - fast boiler, the production of gas hot water boiler, gas steam boiler, condensing boiler integrated, NOx emissions is far below the required standards, environmental protection departments successfully passed the test and get the user's praise.
Vacuum boiler works, features and advantages: vacuum steam boiler equipped with a temperature controller system and a security alarm system is set, when the temperature reaches the set boiler stopping the machine control system will automatically cut off the electrical and gas systems, and issues Audible alarm. Any of a vacuum boiler vacuum gauge, a vacuum switch, a vacuum pump monitoring system, the flue gas temperature sensing probe, etc. abnormal, the control system will automatically cut off the electrical and gas systems, with sound and light alarm. Vacuum adsorption boiler is equipped with a safety valve, start overpressure, to achieve the purpose of safety relief. Preventing overheating protection device, when the boiler temperature exceeds 100 ° C, automatic fuse protection device, the gas system and cut off the circuit, so as to achieve a safety pressure relief, the working principle of vacuum boiler water at atmospheric pressure (1bar), boiling point of 100 ℃. Pressure below 1bar, the boiling point of water becomes less than 100 deg.] C; pressure -0.7bar, a boiling point of 90 deg.] C; pressure -0.3bar, a boiling point of 70 ℃; pressure -0.1bar, a boiling point of 40 ℃ vacuum hot water unit. after the hermetic chamber is formed by a vacuum pumping the vacuum chamber, the combustion heat medium boiling water vapor generates a negative pressure in the vacuum chamber, the vapor condenses in the external heat exchanger, the heating temperature and the cold water pipe to the user through the water after the vapor condenses to form water droplets flow back into the heat medium water, re-heating evaporation, thus completing the cycle, the unit is less than the normal operating pressure -0.7bar. Heating medium water is treated by a special cleaning, deoxidation high water, washed once injection is completed before delivery from the factory, in a closed loop inside the unit during use (evaporation - condensation - vaporization), not increase, not decrease, the unit life without need to be supplemented or replaced.
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 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
When electrically heated vacuum phase transition boiler operation, the internal environment is a vacuum state. At this time, the intermediate medium oxygen in water will be discharged to the outside electric boilers vacuum phase transition, and therefore does not cause oxidation corrosion in the boiler, cause damage to the device. Meanwhile, fired vacuum hot water boiler in ireland heating heat exchanger portion of the material used is stainless steel, corrosion will not occur. Further, the electric vacuum hot water boiler only once was added a small amount of the heat medium water, increase nor decrease is running, the internal no scaling. Second, the fuel (gas / coal) vacuum phase transition boiler
