A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
The SCB-150H-N indoor residential Ultra-Low NOx Combi Boiler uses up to 150,000 BTU/hr of Natural Gas to deliver a continuous supply of hot water and space heating for a home in high altitude regions. This High Efficiency heating system has a 95% AFUE and is ENERGY STAR Certified.
Today’s process and heating applications continue to be powered by steam and hot water. The mainstay technology for generating heating or process energy is the packaged firetube boiler. The packaged firetube boiler has proven to be highly efficient and cost effective in generating energy for process and heating applications.
The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes. Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.
Residential Gas Steam Boilers Residential gas steam boilers pair with steam-based radiators to provide consistent, comfortable heat out into homes. Because steam systems don’t require additional accessories like blowers and pumps, they’re easy to install and require very little maintenance.
Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from …
The usual arrangement is to have a fuel oil supply available on site, and to use this to fire the boiler when gas is not available. This led to the development of ‘dual fuel’ burners. These burners are designed with gas as the main fuel, but have an additional facility for burning fuel oil.

The Fire tube boiler is intended for transmitting hot-gases using heat source as well as cycle. These gases flow through pipes with a water-filled drum. This procedure efficiently transmits the heat from the hot gas to the water, which efficiently produces steam.
This double-flame/smoke tube boiler with separate gas passages is suitable for operation with just one burner. The three-pass principle with a rear flue gas reversing chamber positioned in the water chamber was patented in 1952. The economizer and superheater can be …
