To a boiler, capacity is an important parameter. Boiler’s capacity, also known as the rated capacity, nominal capacity, installed capacity, or maximum effect, is the intended full-load sustained output of a facility such as a power plant, a chemical plant, fuel plant, metal refinery, mine, and many others. Nameplate capacity is the number registered with authorities for classifying the power output of a power station usually expressed in megawatts (MW).
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
Electric describes with the diagram of steam boiler before the operation using the operating electric steam boiler 1. The apparatus used should be turned off drain valve, supply valve, inlet valve open, check the power supply is normal. 2. When the controller stops the alarm by pressing the power switch, the switch to Ⅲ heating profile, alarm controller (due to lack of water in the boiler), while the indicator light replenishment pump starts to operate, to pay low water levels, a high level continues automatic replenishment , water pumps stop, boiler heating lamp is lit, the boiler automatically start heating. 3. When the boiler pressure reaches the set value, the heating switch to Ⅱ, this time to turn the steam valve, the use of steam. 4. When using steam, the furnace pressure drop, when the pressure dropped to the lower limit set value, the heating boiler starts automatically. 5. When steam is used, oven declining water level when the water level falls below the low, i.e. start the pump, a high level of replenishment to the furnace, the boiler heating cycle automatically. When the water level is below the low water level, and supply system is not working properly, after 10 seconds the water level does not reach the low water level electrode, the controller continuously alarm and shutdown protection. 6. Use process to maintain the boiler pressure at about 0.4Mpa, if necessary, by heating the toggle switch adjustment. 7. The use of the process, such as more than 15 seconds duration alarm alarm, should immediately check off the soft water tank is normal. 8. The work is completed, press the power switch off the power, power light is off.
Details of boiler boiler periodic inspection during operation, the pressure member at high temperature and pressure vapor medium effect at high temperature flames external radiation or smoke erosion, corrosion may occur, deformation, wear, fouling, burnt, leakage and other defects, It will appear fouling, coking phenomenon, if not timely detection and timely eliminate hidden dangers, could result in equipment damage, may lead to serious life and property losses. Visible boiler periodic inspection is very important. According to "Provisional Regulations on Boiler and Pressure Vessel Safety Supervision" and "Steam Boiler Safety Technology Supervision", "Hot Water Boiler Safety Technology Supervision" (hereinafter referred to as "Regulations"), the State Quality and Technical Supervision Boiler and Pressure Vessel Safety Supervision Bureau has developed "boiler periodic inspection rules." Fast boiler for you regarding the removal of an important part of a regular inspection of boilers for everyone to share: fourth regular inspection of boilers includes external inspection, internal inspection and hydrostatic test three types: external test means that the boiler in operating state examination of the security situation of the boiler; 2, internal inspection means to inspect boilers security in a boiler shutdown state; 3, hydrostatic pressure test is a test boiler water as a medium, a predetermined boiler pressure strength and tightness testing member performed. Article boiler external inspection is generally carried out once a year, usually internal inspection once every two years, the general pressure test once every six years. For internal inspection of the boiler can not be, should be pressure test every three years. Internal pressure test and inspection cycle power plant boiler may be appropriately adjusted in accordance with the overhaul cycle power plant. Only when the internal inspection, external inspection and hydrostatic testing are within the acceptable period, the boiler can be put into operation. Article 6 except for normal periodic inspection, the boiler of the following circumstances, the following test should be conducted. External inspection: 1, the start reassembling the boiler put into operation; 2, the boiler stopped running more than a year to recover; 3, combustion and boiler safety automation system after the change. Internal inspection: 1, the newly installed boiler after one year; 2, to move equipment before the boiler put into operation; 3, boiler stop running more than a year before returning; 4, the pressure elements are important repairs or renovation and re-run after 5, according to the results of previous internal inspection and boiler operation, there are doubts about the safety and reliability of equipment;; 6 after a year, according to test results and external boiler operation, safety and reliability of the equipment when there is doubt. Hydrostatic Test: 1, reassembling the boiler before put into operation; 2, the pressure receiving element after major repair or reconstruction. Article VII When internal inspection, external inspection and hydrostatic test carried out in the same period, should be followed by an internal inspection, hydrostatic testing and external testing. Article 8 Units and boiler inspectors engaged in inspection work should qualify the project and the corresponding level in accordance with the relevant provisions of the National Board of Boiler and Pressure Vessel Safety Supervision Agency. Article IX of the boiler using the unit, the unit should be carefully examine the implementation of this rule; Boiler and Pressure Vessel Safety Supervision Organization to oversee the implementation of this rule. Article X boiler unit boiler should be submitted in the prescribed periodic inspection of boiler units before the date of the inspection and periodic inspection applications. Use the integrated test units each test date unit boiler inspection plan worked out, and notify the boiler unit.
