industrial hot water coal boiler
What puzzled the industrial hot water coal boiler is more common and must be addressed? Pulverized coal boiler with pulverized coal boiler, which is a concept right? Boiler flue gas flow, which specifically refer to? Well, boiler water phosphate Why controlled between 5-15? In addition, there are other questions related to the boiler. These are important points related to the boiler. Therefore, the following will be specifically answered immediately, so that we can clearly understand.
Hot water industrial hot water coal boiler item to check what internal checks and the use of hot water boilers prepared in the furnace and flue inspections of boiler accessories, check the automatic control system, checking of ancillary equipment, inspection equipment burning auxiliary heating surface check the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling.
Condensing gas industrial hot water coal boiler with coal-fired boilers What are the differences? Some may have which is not very clear to distinguish condensing gas boiler with coal-fired boilers, here we look at their specific differences, 1. The circulating fluidized bed combustion coal-fired boilers are coal by crushing equipment , by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from the flue gas into the atmosphere, polluting the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions from coal-fired boilers is relatively gas boiler, SO3, NOx is much less. 3. Ventilation general negative pressure combustion coal burning boiler, a combustion process with the base by the induced draft fan and the blower mating fit together to complete coal combustion process, requires a lot of air and the furnace wall due to the leakage of flue excess air ratio of up to between 2.1-2.5. Micro-condensing gas boiler combustion positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion furnace flue wall and running flue outlet air coefficient can be 1.05-1.2.4 fuel combustion safety explosion-fired boilers, furnace explosion hazard unlikely to occur. The condensing gas boilers in the explosive concentration limits encountered fire will explode. More dangerous. The boiler control due to coal fired boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to load difficult boiler operating parameters. And condensing gas boiler is less impact on the factors may be adjusted according to the size of the burner valve load, easy to achieve automatic control.
One yuan complex Unrestraint years, the spirit of renewal long. The new year began with new challenges, party fast Group 2019 Spring Annual Meeting held January 29 at 3:30 pm in Anyang, Henan Hong Rui Hotel, all my colleagues gathered to congratulate the New Year.
