When the gas is burned in a gas boiler near a water resevoir, the water is heated; the heat is distributed in one of many different ways, depending on the boiler’s configuration. In industrial settings, boilers are used to generate steam, sometimes at very high pressures, in order to harness the steam for mechanical work purposes. Boilers can also be used to heat water below its boiling point for use in industrial processes; such water can be drawn from taps for use in cleaning and even in restrooms.
Natural gas is used to fuel many different boiler configurations; industrial boilers, low pressure boilers, steam boilers, condensing boilers, and many other kinds of boilers use natural gas for fuel. Industrial boilers will often use natural gas as a fuel because of its availability and its capacity to provide consistent, even heat. Low pressure boilers can also make use of natural gas fuel for the same reasons.
As natural gas increases in cost, property owners and business owners have begun searching for other heat generation methods in order to save money. Also, as interest in sustainability and conservation grows, alternatives to hydrocarbon fuels have started to become popular. The natural gas production process is expensive, resource intensive and often contributes in a substantial way to general environmental degradation and pollution of the areas from which raw materials are extracted. The burning of natural gas also produces harmful emissions, some of which, like carbon monoxide, can work their way into climate control ducts in the event of air filter and heat exchanger malfunction. For these reasons, alternatives like electric boilers and wooden boilers have become popular in certain markets./p>
Both achieve the same purpose, the heating of water, but by different methods. Recent advances in panel technology have allowed for the creation of solar powered boilers, though they can be expensive and are only useful in consistently sunny areas. Gas boilers, despite their drawbacks, remain very popular heat generation equipment because of their effectiveness.
