wns series fuel oil or gas fired hot water boiler

Maintenance of oil-fired boiler! What oil-fired boiler include? Fuel oil-fired boiler comprising a boiler water, wns series fuel oil or fired hot water boiler fuel, the fuel heating boiler, oil bath boiler, and steam boiler fuel, gas oil refers to the boiler fuel (such as diesel, kerosene), heavy oil, residual oil or crude oil fired boilers. Maintenance of oil-fired boilers? After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler.

Fuel gas-fired boiler has been widely used in the country as an alternative to high gas boiler pollution, fuel gas-fired boiler has been widely used across the country. The use of gas gas boiler promotes people's lives. To prolong the life of the boiler, it must be maintained. One might ask, how should the boiler maintenance? First, the main components of the gas boiler: a burner: Burner collector, equipment, oil and gas as a whole. The highly integrated and highly automated boiler system to maintain focus. 2, the boiler body: the boiler is to achieve the main body of the thermal energy conversion member 3, computer control system: the computer control system is the core component of the boiler, the boiler is the command center. Second, to maintain each of the system 1, the burner maintenance: a rotor cup thoroughly clean the burner, ignition means, filter, pump, motor and impeller systems, and adding a lubricant on the damper linkage. Retest combustion. 2, the controller maintenance: inspection and inspection of electrical elements, control lines, purge control ash box, each control point is detected. , Sealing process. Controller assembly prevents wetting. 3, the water supply system maintenance: repair water treatment plant to check whether water quality standards, a comprehensive clean water treatment system, check into the operation of pumps and elevators, check whether the valve of each tube can be used flexibly. Cutting water, the system is filled with water, the valve is closed. 4, oven maintenance: In order to make long-term safe operation of boilers, boiler maintenance must strengthen everyday use. This is also an important measure thermal efficiency and avoid the deterioration of the state of deterioration of the boiler and prevent accidents.

Various components of the electric steam boiler is composed of different materials. 1, in order to prevent the occurrence of electrochemical corrosion, cathodic protection measures must be taken. 2, for the treatment of sewage, electric boiler blowdown bottom of the boiler flue gas condensation can be prevented. Since the flue gas is flue gas condensation (diesel or natural gas) and the flue gas temperature in the aqueous too low, water generated. A portion of the moisture is discharged from the chimney, the chimney wall is absorbed, the rest is deposited on the bottom of the chimney.

Wenzhou City, Zhejiang Province, is one of the countries and determined implementation of the regional focus of the Battle of Blue Sky. In order to improve air quality in the city of Wenzhou, improve people's livelihood well-being, for the governance of air pollution, Wenzhou City, developed and introduced the "winning Blue Sky Battle action plan" (hereinafter referred to as "embodiment"), give the city the power to defend "Wenzhou blue." Program 2020, in Wenzhou PM2.5 average concentration is maintained at 35 micrograms / cubic meter (city maintained at 31 micrograms / cubic meter), air quality control over the ratio of the number of days of 90% (93% city control ), severe weather and pollution more effectively controlled.

"Plan" also lists the specific implementation timetable: by 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, the city's natural gas consumption amounted to 570 million cubic meters. In principle, to new natural gas cogeneration and gas chemical projects. By 2020, the city's total coal consumption decreased by 5% compared with 2015, accounting for the proportion of total energy consumption fell to 42.8% or less.

There are several types of "big coal" will be gradually phased out, including environmental protection, energy, security and other non-compliance of 300,000 kilowatts coal-fired units, 10 steam tons / hour and tea furnace coal-fired boilers, around the built-up area , operating a stove, grain storage and drying equipment, coal-fired facilities, more than 10 steam tons / hour and 35 steam tons / hour of coal-fired boilers. Before the end of 2020, 300,000 kilowatts and above thermoelectric coal-fired boilers and small coal-fired thermoelectric backward within the range of 15 km radius of the heating and power plants all closed down integration.
