gas hot water heater

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of ​​11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired hot water heaters, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

Premix combustion characteristics of the premix before the hot water heater unit module should have the starting conditions premix boiler module are: stable surface combustion, combustion efficiency; compact combustion, high-density flame; load turndown ratio up to 1: 7, high adaptability gas; lower combustion product discharge. Gas through the solenoid valve, the air passes through the venturi, at the blowing action of the fan, into the fan together. The two fan gas blown stir premix chamber, the premix chamber acts as a pressure balance. Through the above process, gas and air to achieve complete premix. Fully premixed gas, fuel gas and oxygen molecules in contact with a large surface area, the combustion reaction is likely to occur. Ignition, fast response, more complete combustion, gas release more complete chemical energy; and a low air excess factor, a small amount of surplus oxygen, less air pollutants produced by the combustion, the flue gas of small size, low heat losses. Premix module weather-compensated boiler, energy-efficient and comfortable. Gas boiler in the heating season outdoor temperature varies from month to month, the same day the outdoor temperature is different at different times of the heat demand of the building will vary widely. Smart central controller with an indoor temperature sensor and a water temperature sensor, real-time collection and heating the indoor ambient temperature signal, automatically calculates the optimum water temperature, and controlling the number of modules put into operation, while maintaining room temperature stability, saves fuel, significantly lower operating costs. Premix module boiler system independent circulation, reduce fouling, eliminating the need for post-maintenance costs. Premix boiler module long life, easy installation, low power consumption, convenient and flexible capacity expansion and other advantages, not only reflects the small size, low cost, energy-efficient features, but also to maximize the use from the early and late maintenance are saving input costs and operating costs.

Some users for a small area of ​​the hot water heater problem, fully condensed after the launch of commercial vertical displacement by condensing hot water boiler and hot water boiler technology upgrades premix, covers can be as low as 2 cubic meters, for the enterprise minus the boiler area is too large problem.

Causes of damage to the furnace wall: in terms of design, the furnace wall and the furnace arch structure is irrational, hindering the normal expansion of the hot water heater pressure member; fewer waterwall tubes disposed; burner position is not correct, so that part of the furnace wall and the furnace arch overtemperature high. In the operation, the combustion flame is adjusted properly, the flame center offset; long pressure combustion, the furnace temperature is too high, low ash melting point, severe coking furnace; fire, and increasing shutdown, load shedding too fast, so that the furnace walls, furnace arch cold and hot; decoking damage the furnace wall when the slag; explosion of combustible gases in the furnace due to the impact. In terms of installation and maintenance, broken brick edges, cracks between the blocks too; improper preparation of mortar proportion of poor maintenance, brick bond is not strong; do not leave enough expansion joints; oven time is too short, the furnace wall are not completely dry, ie liters pressure operation.
