Water Tube Boilers | Spirax Sarco
Because of the relatively low temperature of the gas turbine exhaust, compared to the burner flame in a conventional boiler, a much greater boiler heat transfer area is required for a given heat load. Also, there is no need to provide accommodation for burners. For these reasons, water-tube boilers tend to provide a better and more compact

How Does a Boiler Work? A New York Tech Explains – Ranshaw
An electric boiler creates heat in a slightly different way than their oil or gas counterparts. Instead of burning fuel, they use electrical power to heat elements. Those hot elements then transfer heat directly to water. While electric boilers burn "cleaner", they're not as efficient and are more expensive to operate than oil or gas boilers.

Steam Boiler: What Is It? How Does It Work? Types Of
In the case of a steam boiler, the tubes in the boiler absorb radiant heat from the flame produced in the combustion chamber. The heat from radiation heating depends on the rate at which the electromagnetic waves are absorbed. Convection. Convection is the transfer of heat within a liquid or gas when the liquid or gas …

What is a heat exchanger in a boiler? | Viessmann
A boiler works by using hot gas to heat water - and a heat exchanger is what allows this to happen. As the gas is heated, it begins to rise. When it rises, it reaches the heat exchanger and is pushed through the coiled pipe. Cold water is surrounding the pipe and, as the hot gas moves through it, it gradually heats the water, which is then

Heat Pump vs. Boiler Comparison: Which is Better
Modern high-efficiency boilers (gas, LPG and oil) and biomass boilers have a much-improved efficiency of around and above 90%, with only small amounts of heat lost through the flue. On the other hand, the efficiency of heat pumps can, in effect, reach as high as 350% (or in technical terms, a Coefficient of Performance of 3.5).

Elite FT High Efficiency Natural Gas Condensing Heating
Condensing gas combi boilers used to have two heat exchangers, as it's thought that this was more efficient. To begin with, the water was heated in the primary exchanger. As hot waste gases were produced, the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger, which only used waste gas to heat the water.
