Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original boiler equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
1, the temperature rise is too fast, the radiator cold and hot temperatures, easy to leak;
2, the pressure rise is too fast, the heat sink is likely to cause metal fatigue, reduced life, it is likely to cause the radiator burst;
3, the radiator surface temperature is too high, easy to burn the people, but also result in poor weather conditions indoors, house dust exploded above the radiator, resulting in blackening the wall above the sink;
4, if the heating steam sending heating pipe before ineffective, can cause water hammer when the feed gas, water in the radiator is formed of water vapor under the impact hammer, and the impact of the radiator pipe, noise, implicates the night rest, also damage radiator and pipes;
5, the water heated in the boiler to absorb heat of the fuel discharged, and the water molecules have to absorb a portion of the heat into steam, resulting in energy waste.
By the formula we can see, natural gas boiler gas consumption depends mainly on the capacity of the boiler, the heating value of natural gas and boiler efficiency. But the calorific value gas boiler capacity and we can not change, only the boiler efficiency is in the variable state.
1 ton gas boiler, full load operation, gas heating value is calculated according to 8000 kcal per cubic meter, depending on the efficiency of the boiler, after calculated: 1 ton Gas boilers consume about 75 cubic meters per hour.
