gas heating boiler system wholesaler

Fuel gas control step and the blowing process air volume of the total fuel gas steam heating boiler system wholesaler steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.

The reason the gas heating boiler system wholesaler burner noise increases are what it? When making use of gas-fired boiler, we found this small fire normal, but this time turn the fire, extinguished or flashing instability. First speaking, that is because of this fire damper of the air volume setting is too large; i.e. after an oil fire because the micro-switch valve (air outside that group) inappropriate setting (set lower than the fire damper of the air volume is also Big)

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.
