The difference between hot water and steam automatic condensing boiler suppliers of the boiler as a heat medium for air conditioning, heaters, low temperature oven drying equipment, textile and the hot water tank is heated by a variety of low-temperature, heat transfer and air-conditioning coil equipment. Hot water as a heat medium has the following advantages: 1. Generally the lower the heat medium water temperature of the heat medium, and large temperature difference between the flue gas, boiler exhaust gas temperature is relatively low, and thus higher boiler efficiency. 2. Closed hot water supply system small amount of water and sewage rate is much smaller than the steam boiler, waste water is also smaller. And lower boiler water quality requirements, less the cost of water treatment. 3. The specific heat capacity of water is large, a large hot water system capacity, strong heat storage capacity. When the thermal conditions or hydraulic failure condition a short time, without significantly heating conditions cause large fluctuations. 4. pump hot water heating system can be used for long-distance transportation, a small heat loss, heating large radius, to adapt to the requirements of urban planning central heating. The hot water temperature is low, less heat transfer coefficient, thermal efficiency is relatively low as the heat medium heating major drawback. Present predominantly of boiler steam boiler, steam as a heat medium main advantages are: a low cost, wide adaptability, can meet the heat requirements of the various users have different requirements for temperature and pressure simultaneously; 2 nontoxic. directly heating food, even if leaking would not harm the environment; 3 high steam temperature, a large latent heat of vaporization, the heat transfer area can be reduced relative to the hot water device, reduce costs; 4 hot inert small, heat faster when the steam supply, the cold disappear just as quickly when the steam stop. Since the heating medium steam condensate recovery is difficult, resulting in waste and water latent heat. Even with condensate recovery, condensate recovery in the process, because water easily dissolved oxygen and other impurities, but also easy to cause harm to the boiler. Oxygen to the water, salt and other impurities cause boiler fouling, corrosion and other problems affecting the safety and energy efficiency of the boiler.

4, condensing or non-condensing?

When designing the heating system return temperature is less than or equal to 50 ℃, using suitable condensing boilers.

Low nitrogen automatic condensing boiler supplier technology made a major breakthrough, however gratifying that through the unremitting efforts of domestic boiler companies, China's low-NOx combustion technology gradually into the world advanced list, catch up with a lot of foreign advanced technology.

Operating Cost:Let's face it, some of the claims being made about efficiency would make a seasoned politician blush. Unlike a car, the "gas mileage" of your average automatic condensing boiler supplier will degrade over time due to scale and sludge deposits. Putting aside for a moment that many "high efficiency" horizontal straight tube boiler will also require high cost maintenance, a boiler's operating cost can be boiled down to this simple equation: Fuel burned in a new boiler = cost to operate new boiler. Fuel burned in that same boiler that is scaled will cost X more dollars to operate. A boiler can begin to scale up in a matter of months or even weeks. A scaled boiler can turn X into a big, unpleasant number. Don’t buy a boiler that can’t be solved for X … or you’ll be asking yourself why.Scale:aka “lime” “mud” “sludge” “bane of man’s existence” – occurs when dissolved solids (the "hardness" in water) settle out in a pressure vessel. It’s the familiar process that ends the life of most water heaters – and boilers. Solids like to drop out of suspension and plate onto the hottest heat transfer surfaces, and as they accumulate, the water will absorb less energy and the efficiency will drop from good – to fair – to poor. When this happens, the heating surfaces begin to overheat. If the scale can’t be removed, stay tuned for tube or pressure vessel failure. At this point, many boilers are scrapped because the cost to replace can be cheaper than the cost to repair – although cheap is hardly the word that will come to mind of the person paying for it! This is why the engineers at Rite developed the boiler they did: A boiler that can be easily cleaned, field repaired and more than capable of maintaining its brand new efficiency year after year after year. A boiler designed to last a lifetime.
