Which uses common knowledge on maintenance and gas hot water boiler there?

Gas hot water boiler by the pump, burner, heat transfer equipment, automatic control of electrical and complex mechanical structures in one of the high-tech a hot water supply, heating, with heating, hot water conduit system is correct or not will greatly affect the correct connection, installation, commissioning, operation and maintenance and other safety performance and service life.

Hot water boilers are mainly used for heating and bathing. The hot water of the water tank can be heated by circulating hot water circulation pump and the hot water of the tank is heated again and again, which can realize the goal of bathing. The hot water circulation pump circulates the hot water of the heating pipe, and the radiator (radiator) can meet the requirement of people's heating, and the hot water boiler and the hot water circulation pump cooperate with the heat exchanger can realize the double functions of bath and heating. In the natural circulation hot water boiler, the inlet and outlet water are piped from the top of the pot. By the water intake pipe, the inlet water drop pipe is guided into the front and side of the header, and heated up through the water cold wall tube. Before the drum, the back end is down and up The riser boundary is provided with a water barrier, and only the lower part of the drum is cut off. For forced circulation, the inlet water is connected to the front lower header, the front water wall pipe rises to the top of the drum (when the front water wall drop pipe is cancelled), and then it is transferred to the side water wall drop pipe to the side bottom header, and then the side water wall pipe is put up to the up drum. From the front of the convection tube down to the down drum, finally, the bottom of the pot between several torches of water from the back of the pot.

Luoyang, Henan Province issued the "Luoyang coal consumption reductions embodiment (2019-2020 years)", the program proposes: To continue to promote alternative coal consumption reduction, the implementation of industry "electricity instead of coal" project.

2016-2018 years, the city of Luoyang excess capacity, coal-fired boiler demolition, energy saving, clean energy alternative through a series of measures to resolve the power industry, pushing the total coal consumption control achieved some success, but the energy mix partial coal, thermal power installed capacity of migraine and thermal power multi siege pattern has not fundamentally changed, there is still emphasis on the industrial structure, high energy-consuming industries continued to increase the proportion of energy consumption, coal consumption is highly concentrated and other issues. Especially since 2018, comprehensive energy consumption of coke, chemical high energy-consuming industries rise significantly, the whole society electricity demand continues to grow, the amount of coal for power generation system tune up utility power plants rise, not fall, some counties (cities, districts) large-scale industrial coal consumption rise, not fall. Therefore, Luoyang City will continue to work to phase out coal-fired boilers to improve the quality of atmospheric environment.

"Plan" put forward the overall goal of coal governance: By 2020, the city's total coal consumption and strive to 2015, down from about 23% control in less than 20.3 million tons. Among them, the total consumption of non-coal power industry control in less than 9.6 million tons, the total coal consumption in coal-fired units ganged public control in less than 10.7 million tons.

"Plan" requirement, the industry needs all kinds of hot water, steam, hot air in the production process, and gradually promote regenerative and direct thermal electric industrial boiler applications. In the metal processing, casting, ceramics, refractories, glass and other industries to promote electric furnaces, industrial kilns and encourage qualified to carry coal to electricity.

Vigorously promote clean heating pilot city construction, 2019, 2020, respectively, the implementation of urban and rural residents electricity instead of coal, 110,000. 2019, 2020, respectively, to complete the electrical heating 500,000 square meters, 800,000 square meters.

In addition, the "plan" also proposed to accelerate the development of clean energy and new energy, the implementation of comprehensive improvement of coal-fired facilities, the city will no longer approve the domain, and the new 35 tons of steam coal-fired boilers, accelerate the elimination of 35 tons of steam / h and coal-fired boiler.

The way to recover condensate from Boiler

how to recycle: The boiler condensate recovery system recovers the high-temperature condensate discharged from the steam system, which can maximize the utilization of the heat of the condensed water, save water and save fuel. Condensate recovery systems can be broadly classified into open recovery systems and closed recovery systems.
