This chapter Xiao Bian gave you these three cases is the number of boilers are air consumption: regular manufacturers of 6 tons of gas boiler is a standard, rated steam pressure of 6 tons of gas boiler is 1.6MPa, rated steam temperature 204 ℃, the thermal efficiency is depending on the manufacturer's technical standards and different, according to well-known manufacturers Henan party fast factory technician stated that its company produces thermal efficiency of 6 tons of natural gas boilers up to 95%, may in some do not understand the line the customer's eyes, a few percent is not obvious, but once put on the industry able to have a very large customers to reduce fuel costs per year, compared to the technology in terms of well-known manufacturers chose better. Closer to home, gas boiler according to the air consumption parameter table displayed on the technical side of Henan fast calculation formula, a calorific value parameter is gas 35438KJ, and the consumption of natural gas boilers is 75 cubic meters per ton, if it is, then the consumption of the boiler 6 t 450 cubic meters, while gas-fired air consumption are calculated by the hour, so air consumption summary, six tons of gas boiler is 450 cubic meters per hour.

Recently, Anshun City, Guizhou Province, Anshun City, issued a notice to win the embodiment of the three-year action blue sky Battle, as follows.

First, the implementation of the total coal consumption control

Accelerate coal mergers and acquisitions, consolidation pace of technological transformation, and resolutely eliminate excess capacity to resolve the coal. Before the end of 2018 to complete the county level and above cities restrict coal-burning zone and the coal area delineation work to strengthen the loose coal burning and fireworks control, prohibit the sale, banned the use of coal, petroleum coke, high-polluting fuels. Vigorously implement the "coal to gas," "coal to electricity" project, increase the proportion of electricity, natural gas in energy consumption. By 2020, the city's coal accounts for the proportion of energy consumption is reduced to 70% or less.

Second, to carry out comprehensive improvement of coal-fired boilers

Before the end of 2018, the central city out of 20 tons of steam per hour of coal-fired boilers, 35 tons of steam per hour to start the following phase-out of coal-fired boilers. Atlantic Town Center City led Xixiu on the wind direction, seven Town, Cai town official reference implementation of February 15, 2015 promulgated the "Anshun City People's Government on delineation of high-pollution fuel combustion zone ban of" 3.5 Kunming Shanghai high speed range on both sides of one thousand meters anshun prohibit new paragraph 35 tons of steam coal-fired boilers. By 2020, the county (district) total phase-out urban area and 10 tons of steam coal-fired boilers, basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment. Center City ban on new built-up area per hour and 75 tons of steam coal-fired boilers, county (district) urban area 35 tons of steam per hour ban on new coal-fired boilers and other regions 10 tons of steam per hour ban on new coal-fired boilers . Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage.

Third, improve energy efficiency

Continue to implement the action of the total energy consumption dual control and strength. By 2020, the city's yuan GDP energy consumption fell 14% in the region, the total energy consumption control in less than 28.55 million tons of standard coal, new energy consumption control in less than 100 million tons of coal. Strengthen the implementation of energy efficiency standards to promote, develop, promote energy-saving technologies and products to achieve key energy industries, energy-saving equipment standard full coverage.

Fourth, accelerate the development of clean energy and new energy

As of 2020, the installed capacity of wind power reached 200,000 kilowatts; actively seek Zhenning County, Guanling County, Ziyun County PV poverty alleviation projects Indicators Program, to encourage qualified enterprises to implement photovoltaic bidding, led a group of farmers light, light forest project floor building.

Continuous feed water introduced with the progress of the automatic control system an amount of evaporated induction heating steam boiler, especially after the selection of oxygen and other equipment, and to ensure the quality of steam to ensure proper operation of the deaerator, the feedwater must require successive active control system. The float system wide selection inductive sensor. It is somewhat a valve three conditioning system consisting of float sensors, controllers and electric control. Its operational principle is: the float displacement signal charge → → → inductive signal controller has opened, stop, three off switching signal, monitoring the subject for Free actively operating the steam boiler feed water control valve opening degree, the amount of water to adhere to the load requirements satisfied, so that adhere to the boiler water level in the range of 10 ~ 15mm, and the pump can be successive operations.

Common gas boiler maintenance methods

When you purchase the boiler equipment, will pay attention to a lot of problems, the number of thermal efficiency, energy saving and environmental protection whether, if the boiler manufacturers have to install special equipment manufacturing license, etc., are all you need to pay attention to the selection of points. But at the same time, the boiler in the course of regular maintenance is also very important.
