Gas steam boiler

  • Fuel combustion: Fuels such as natural gas or propane are burned in the boiler to produce high-temperature combustion gases.
  • Heat transfer: The heat of the combustion gases is transferred through the combustion chamber wall to the water in the water pipe.
  • Water heating: Water circulates in pipes and reaches the boiling point to produce steam after being heated.
  • Steam Generation: The generated steam is collected in a steam drum and then transported through pipes to where it is needed.

Electric Steam Boiler

  • Electric heating element: The boiler has a built-in electric heating element that generates heat energy through current heating.
  • Heat transfer: The heat energy generated by an electric heating element is transferred through direct contact with water.
  • Water heating: Water is heated to the boiling point, producing steam.
  • Steam generation: The generated steam is released directly into the steam system for supply.

3. 4 Different Environmental Impact

Electric steam boilers are considered more environmentally friendly as they produce zero emissions at the point of use. However, the overall environmental impact depends on the source of electricity generation. If electricity is derived from renewable sources, the environmental impact is further reduced. In contrast, gas steam boilers emit combustion byproducts, including greenhouse gases, contributing to air pollution and climate change.

3.5 Installation and Operation

Electric steam boilers are generally easier to install and operate compared to gas steam boilers. Electric boilers do not require a flue or chimney for exhaust gases, and they have fewer safety considerations related to fuel storage and combustion.
