(6) replacing air preheater wave plate, rinsing, the check processing sector plate, curved plate is deformed, and bearing wear off defects, defect inspection process automatic adjustment mechanism sealing gap. (7) Pulverizing System: Mill off the door, the hot air and the cool air shutter opening degree adjustment. Roller cover and bowl mill liner replacement, the spring biasing force and gap adjustment. Import a fan baffle opening adjustment. (8) the flue expansion joint leakage defect inspection process. (9) soot blowers and related equipment check process. 4, transformation (1) Burner deformation, wear process, replacement, and a bluff body concentrator ceramic sheet, and silicon carbide wear measures. (2) the heated area ash slagging comprehensive inspection process. (3) waterwall, economizer, reheater, superheater tube cutting test monitor segments corrosion and scaling inside the case. (4) boiler, air preheater Leakage leak plugging governance. (5) on the "four leak" taken by plugging repair. (6) backpass wear parts wear welding process and do. (7) heating surface (economizer, superheater, reheater) for transformation, reduce exhaust gas temperature. (8) to do a good job adjusting the air according to test results dynamic field. (9) boiler, the flue joints and other advanced seal plastic material, to reduce leakage.

Recently, Zhongshan City, Guangdong Province, the ecological environment expanded Bureau held a working high-pollution fuel combustion zone ban will promote further urge the major companies on time and quality completion of boiler rectification task. It will be mentioned in the need to deeply Publicizing the newly revised "Air Pollution Prevention Regulations of Guangdong Province" and "boiler air pollutant emission standards" and to implement the next phase of work to expand the scope of the ban on burning zone, Zhongshan City.

District policy is to implement the ban on burning blue sky, Zhongshan City, to win the Battle of the most important, relevant departments, district towns, enterprises should pay full attention and positive action in order to "limit Forced, territorial responsibility, multi-pronged approach , coordinated implementation of the "principle, should work together to create synergy, take the following measures to ensure that all targets are met within the deadline.

According to published Zhongshan City, "about expanding the scope of high-pollution fuel combustion zone ban notice" requirement, in addition to coal-fired cogeneration thermal power plant units have been built high-pollution fuel industrial equipment must be removed or completed by June 30 this year clean energy transformation, all enterprises should actively cooperate with government departments to complete the rectification task on time and quality.

According to requirements "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019), and from April 1 this year, the province's start step by step implementation of the new air pollutant emission standards boiler, new boiler effective from April 1 this year, in accordance with the different regions in which, since 1 July 2019 or 1 July 2020 to implement the new standard boilers. Compared with the original standards, new standards particulate matter, sulfur dioxide, nitrogen oxides and other pollutants received strict emission limits help to further reduce the total emissions of air pollutants.

Use fired industrial hot water boiler prices and hot water boiler structural principle profiles include hot water boiler electric water boilers, hot water boiler fuel, gas hot water boilers and coal-fired hot water boilers, hot water boilers that produce hot water boilers, it refers to the use of fuel the heat released by combustion or other thermal energy (e.g., electrical energy, solar energy, etc.) the water was heated to a nominal temperature of a thermal device. Use hot water boiler and hot water boiler heating bath mainly two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Principle structure of the natural circulation of the hot water boiler hot water boiler, inlet and outlet are taken over from the top of the drum, the water from the water distribution pipe guide and drop into the front side lower header pipe, through the waterwall tubes heating rise. The front drum, rear end plate is provided with impermeable boundary falling rising flow, only the lower half of the drum cross-impermeable partition plate. For the forced circulation, the water access to the front end of the lower header, the front drum increases to upper waterwall tubes (waterwall downcomer Cancellation time), and then transferred to the waterwall tubes downcomer side to side lower header, then into the side of the cloth water wall tube rose to the drum, and from the front row convection bank down to the next drum, and finally between the upper and lower drum and several circuitous flow of water from the rear end of the drum. No circulation boiler with economizer.

(2) major components: the gas burner 5 is constructed of the following system components: 1, the function that the air supply system, air supply system into the wind speed a certain amount of air to the combustion chamber, its main components are: a housing, the fan motor, fan impeller, air guns fire tube, damper controller, damper baffle, a cam adjusting mechanism diffuser plate. 2, the ignition system functions in that the ignition system ignites a mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. 3, system monitoring function monitoring system is to ensure that the burner safe and stable operation, the main components are flame detectors, pressure monitors, temperature monitors and the like. 4, functions of the fuel system of the fuel system is to ensure that the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. 5, electronic control system electronic control system command center and the focal the above system, the primary control element is a control box, with different programmer for different burners, the common programmer has: LFL series, the LAL series, LOA series, LGB series, the main difference is the time of each different program steps. 1, AC 220V power supply is turned on, the buzzer beeps once. 2, press the start button, the buzzer sounds, power controller, the LCD display is opened. At this time, the controller is in standby. 3, the controller opens, through the keyboard operator can enter the running state (open furnace), out of service state (shutdown), the pump manually set the time, access to the recording operation of the alarm and the like. Fireman who usually just press the start key to start the oven, press the stop button shutdown, is very simple. 4, press the start button, to enter the running state, the controller controls the start and stop of the burner according state boiler water temperature, controlling start and stop the pump in accordance with the temperature of boiler water level or state. 5, press Stop key to exit the operating state, the controller closes the burner and the pump (with the exception of pump delay). 6, in the standby state or alarm press the stop button, the LCD display is turned off, the controller off. 7, manually operated pump device selection key press, the pump mark blinks to indicate that the selected pump operation. Proceed as + key auto / manual switch (when the pump is in the manual mode, the pump below the graphic display flag Manual); button can also be provided to manually activate or deactivate the pump (pump case immediately into the manual mode). Press the device selection key to exit the pump operation.
