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 portage and main 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.
The size of the portage and main boiler pressure about the size of the load, is adjusted by adjusting the pressure regulator to achieve. When adjusting the load, simultaneously adjusting air pressure, air volume control must be synchronized, to ensure proper gas to match the air flow, so as to achieve economic operation of the boiler. In normal operation, the gas may not be a sharp turn up or down, in order to avoid abrupt change in combustion, the pressure receiving member suddenly damaged dilations.
The water vapor partial pressure may know, portage and main boiler exhaust gas dew point temperature is generally 55 ~ 60 ℃. We reduced by the refrigerant medium (e.g., cold water, cold air, etc.) to a flue gas temperature of flue gas temperature below the dew point, the condensed water vapor in the flue gas can be recovered sensible heat and latent heat of the flue gases at the same time. Calculating the thermal efficiency is low calorie fat conventionally as a reference, is included in the latent heat efficiency of the boiler after steam heat may exceed 100%. And because the water vapor condensation process condensed water may absorb a portion of the harmful gases (e.g., S02, NOx, etc.), reducing the pollutant emissions, environmentally friendly. Per standard cubic meter of combustion gas can be generated in Northern approximately 1.6kg of water, gas boiler fuel consumption of about 0.7MW 80m3 / h, if half of the generated steam is cooled down, may be generated 80 × 1.6 x0.5kg / h = 64kg / h of water, you can see the amount of water available is considerable, if taken measures to make use of this part of the water, the water shortage in some areas will have a positive effect.
Pressure, atmospheric water heating system with a detailed comparison of pressure 1, pressure portage and main boiler heating system in accordance with comparative analysis of the boiler pressure level, the pressure inside the hot water boiler large pressure is necessary to provide a safety valve, pressure gauge, thermometer, and other auxiliary tool. Since the internal pressure of pressurized hot water boiler is always filled with water, it is not necessary to provide water level gauge, pressure hot water boiler equipped with a thermometer and a water level gauge only, due to the communication, between the boiler pressure hot water boiler and the atmosphere internal pressure is boiling. er and thermometer. Equal to the atmospheric pressure, there is no explosion of the boiler, there is no need to install a safety valve or pressure gauge. Thus, the pressurized boiler heat better than the internal pressure, the requirements of facilities is also higher, there are some risks to the safety of the boiler. The boiler pressure due to internal pressure and atmospheric same security risk is very low, less demanding facilities, but the operational efficiency has to be improved. 2. The circulating pump Comparative contrast, more advanced pressurized water heating system, using the circulating pump main apparatus can be sent to the boiler water system, which generally can be maintained at the operating temperature effect 70 ℃, water pump can be selected . Pressure can be controlled circulating pump water heating system vascular resistance, and to maintain the pressure inside the boiler, in order to protect the water vaporized in the boiler does not occur. (Water gasification boiler First, it will increase the internal pressure of the boiler, increase the risk of explosion; the second is endothermic cooling water evaporation, increases heat loss inside the boiler) and at atmospheric pressure boiler heating system circulating pump, mainly through the boiler water extraction, its working temperature is usually about 95 deg.] C, it is necessary to select the heat pump, which is capable of overcoming the major resistance of the outer loop, but also to overcome the resistance of the backwater control valve. In pressure boiler heating system, due to the relatively low pressure water circulation pump, therefore, very prone to cavitation problems, we can say the inner workings of the environment is very bad. China's relevant scholars these two boiler heating system were analyzed and compared, including mass flow contrast and contrast power. After comparing the work found in the same heating project, the circulating pump energy heating system boiler pressure loss is large. The larger the size of the heating system, the greater the heating area terrain changes, the greater the difference between the two, which is the higher pressure boiler heating system energy consumption. In addition, due to the cavitation problem occurs pressure boiler heating system, therefore, we can not use water pump. 3. Comparison of the effect of heating hot water boiler heating system will eventually be implemented in the heating effect, heating under the same conditions, the performance of the boiler with the capacity of the heating system pressure higher than atmospheric water heating system, therefore, the boiler pressure poor heating effect of heating systems, it must adopt the operation in the form of low temperature for long. Typically, in the same environment, and the heating capacity of the boiler on the basis of the effect of atmospheric heating boiler heating system can only reach about 80% of the water heating system pressure; 11 / December, atmospheric temperature than the heating boiler heating system pressure low temperature heating boiler heating system 10 ℃, said heating effect can be very different. 4. Compare the above to improve safety too, due to the pressure bearing boiler heating system is relatively large, with a certain degree of explosion risk, therefore, pressure hot water boiler manufacturing must comply with national production standards required in the production process supervised check. Before pressure hot water boiler applications, device management need to be registered, and need to be put into application performance check in periodically, hire a professional boiler technician to carry out inspections. Visible, pressure boiler heating system application and maintenance costs are relatively high. For pressure boiler heating system, because connected to the atmosphere, and therefore, there is no pressure difference, no explosion risk, high security operation. Therefore, pressure boiler heating system is not included in the scope of regulation to force, it will not require complex management procedures pressure boilers, low running costs and more. 5. Applications parity pressure boiler can not only supply the high-temperature water, but also to supply low-temperature water. However, pressure boiler heating system capable of supplying only a low temperature below 100 deg.] C in water. 10 years ago, most of the area or businesses are using low-temperature water heating, but heating demand as people continue to increase, energy saving ideas popular, high-temperature hot water boiler has become an inevitable trend. Since the pressure boiler heating system can only provide low-temperature water, and therefore, are applied in conventional cells, that is, multi-storey buildings; high-rise buildings typically employ pressurized heating boiler heating system. Due to pressure boiler heating system no risk of explosion, not mandatory rules and regulations related constraints, therefore, it can be installed in the building basement, especially in densely populated areas, can effectively reduce the loss of heat transfer problems in the multi layer architecture has a distinct advantage.
When that boiler (a different brand which came with our home) sprung leaks inside and rusted out and we built a new house and needed a bigger model, we knew we definitely wanted another one.
