Thermodynamic Design of a FireTube Steam Boiler
Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering team’s design.
Fire-tube boiler - Wikipedia
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 fire-tube boiler developed as the third of the four major historical types of boilers: low

Boilers
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

BOILER EFFICIENCY GUIDE - Cleaver-Brooks
Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

Calculating Boiler Efficiency - Forbes Marshall
This method calculates boiler efficiency by using the basic efficiency formula-η=(Energy output)/(Energy input) X 100. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100

2.3 Boiler Types and Classifications There are virtually infinite numbers of boiler designs but generally they fit into one of two cat-egories: Fire tubeor “fire in tube” boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam cir-culates. (Refer Figure 2.2). Fire
