Fire Tube Boiler - Boilersinfo

Fire Tube Boiler. 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.

Q1: What is the boiler efficiency? -

The hardness adhered on the resin flows out and the capacity of the resin restores by sea water going through the resin. The soft water can be supplied into the boiler at the all time by regeneration. However, the capacity of the water softener also declines year by year. This is the resin deterioration year by year.

Q1: What is the boiler efficiency? -

Then, we will reply you the followings concerning Boiler Efficiency which is closely related with the boiler saving energy. Definition of Boiler Efficiency is "The percentage of the total absorption heating value of outlet steam in the total supply heating value." In other word, it is a rate how the boiler runs efficiently.
