Shandong Mining Group in the six months after the boiler use, users submit a report to our company, our company started in 2017 using WDR0.5-0.8-Ⅱ electric fast Boiler Co., Ltd. of heating steam boiler. Large output, stable and reliable, high degree of automation, simple operation, do especially in terms of security is in place. After-sales service is very timely response to our technical consulting reply quickly and accurately. Whether it is party party products or fast fast service. My company is very satisfied. --customer feedback
Boiler ignition How hard? Preparatory work must be done in place! We see, out of sight, the boiler provides a steady stream of power, supporting all aspects of our daily life and industrial production needs, making great contributions to urban development and social progress of civilization. When you buy the right to their own businesses boiler equipment, how to properly operate the boiler operation becomes very important. In order to ensure the normal operation of the boiler, before ignition must be strictly checked and fully prepared; to do the following seven steps before you can begin to start the ignition. A, check and adjust the water level in the boiler water level adjusting on the display of digital boiler water gauge, when the boiler water level below the normal level required, when the water level above the normal water level will have to open the drain valve timing drainage, the water level reaches a predetermined. The water level should not exceed the normal water line when the boiler for the first time (cold oven) Sheung Shui. This is because the boiler ignition, water boiler thermal expansion is likely to exceed safe water line. Once this happens, the water level should be adjusted by sewage. If the water table level and table column is connected, to check whether the valve opening meter column connected tube. If the water table glass contamination, poor resolution, and must be cleaned or replaced with new equipment. Second, the former boiler blowdown test run, the test should be done on the sewage discharge valve, the valve is fully closed after confirming good, be careful not to have leakage. Third, check the pressure gauge to check the position of the pressure gauge; boiler no pressure gauge pointer should be limited stop limiting, the staple of the staple, the pointer value from zero gauge should not exceed the predetermined allowable error. When the gauge does not meet the requirements should be promptly replaced. Note that the header gauge cock in the open position. Fourth, check the water supply system of water storage tank to check the adequacy of whether the water supply piping and valves open. Manual and automatic water supply for the test, to confirm its good performance, the correct action. Fifth, check the furnace flue damper open ventilation will begin ventilation, have induced draft fan should start induced draft fan for ventilation. If the natural ventilation flue long and winding, ventilation time is generally less than 10 minutes; the wind if mechanical ventilation, generally less than 5 minutes. Six, ventilation equipment inspection and inspection of all fuel grate transmission section condition, to remain intact, normal rotation job. Reserves the liquid fuel tank should be checked, the gas fuel check gas reserves, and while confirming the oil pressure is normal. Fuel lines, filters, fuel pumps, the valve opening and closing the pipeline should be checked to ensure that no exception. Start oil heater, oil maintaining an appropriate temperature. Check the opening and closing of the control valve to meet the requirements. Confirm alarms work properly. Check flame monitor light-receiving surface and protects the lens is clear and transparent. Restrict the chain system is normal. Seven check automatic control device close the power switch, the power indicator confirmed by the control panel is turned on. Check the medium (air) and the fuel line for each valve opening and closing state of the pipeline, which confirmed that no leakage, no abnormal. Check the water level detection device, the specified maximum and minimum water level at the limit, the ability to correctly stop the pump and start pumping. Check the opening and closing of the control valve to meet the requirements. Low water level alarm can confirm correct operation. Check flame monitor light-receiving surface and protects the lens is clear and transparent
How to maintain electric water boiler shutdown after the weather gets warmer, electric fired hot water boiler 15 ton heating season many are also beginning to use the outage. But even the shutdown of the boiler, we can not ignore the maintenance of electric water boiler, furnace inside and outside to prevent corrosion problems arise. Well, you know how the future electric water boiler shutdown maintain it? 1, the electric water boiler shutdown after cooling, the elimination of the heating surface fouling and ash grate the upper, lower part of the furnace. 2, to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. If quicklime as a drying agent, needs to be placed within about 3kg lime per cubic meter flue or furnace, should be closely placed after all the vent door closed. Need to be replaced after lime turn pink. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. 3, as anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. Wet maintenance for a period not exceeding one month shutdown of electric hot water boilers, boiler water shutdown after the release, discharge and clean fill with water, cut off the power, close the valve. Dry refers to the maintenance, shutdown the released water put in the furnace dirt rinse the pot burner Weihuo dried, and then the whole gas boiler drained, the valve is closed to all pipes, every three months check again. The above is fast boiler for your finishing, electric water boiler shutdown after proper maintenance measures, we hope everyone can grasp and strictly enforced, care for their own boiler plants.
Gas steam thermal cracking reaction furnace gas steam oven should be carefully introduced reflect in the use, to guard against water, acid, alkali and leakage into the low boilers using the system, the system should be installed filters installed to prevent debris into various types, to ensure the purity of the oil . Gas and steam is easily oxidized during heating, the acid value of the oil is increased at high temperatures and a large change rate. Steam oven gas kinematic viscosity gradually increases, which is due to the thermal cracking gas vapor component at high temperature, thermal polycondensation reaction. Thermal cracking reaction resulting in generation of small molecule compounds, to reduce its viscosity; oxidation temperature when the inner conduit thermally cleavage occurs at 300 ~ 400 ℃, coke formation in the pipe, the inner wall of the device, leading to heat accumulation pipe affect the heat transfer efficiency, sludge poor flowability, transfer oil accelerated aging failure, but also to the furnace, pipes local overheating, impairing the mechanical strength of the threat to personal safety.Free Chat
