You can boost the overall efficiency of a steam boiler into the 90% range by adding a separate heat recovery unit to the flue gas. This will give an overall efficiency corresponding to the reduced exit flue gas temperature and will condense some of the water in the flue gas if the temperature is low enough.
If the amount of steam produced in the boiler is as great as that leaving the boiler, the boiler will remain pressurized. The burner will operate to maintain the correct pressure. This also maintains the correct steam temperature, because the pressure and temperature of saturated steam are directly related.

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.
(Saturated Liquid) Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses
A: By having an efficient steam system in operation, an average-sized plant can expect at least 10% to 30% savings. There are multiple ways to accomplish this: 1. Maximizing boiler efficiency. 2. Staying within the fuel range. Fuel companies are imposing tariffs if fuel consumption goes above allowed levels.

Module 5 - Boiler optimisation (PDF) - Sustainable Energy . 2017-8-28 · The loss of boiler efficiency is approximately 1% for every 4.5°C increase in stack temperature above if a 150 psig saturated steam boiler generates 4550 kg/h of steam and has a blowdown rate of 10%, the heat recovery potential
Aug 26, 2011 · An understanding of the load vs. efficiency relationship is a guide for better decisions about boiler operation. The oxygen content in turbine exhaust gases is sufficient to support the combustion needed for a downstream waste heat boiler. The heat recovery steam generator uses about 8% to 10% less
Stack Temperature It really boils down to stack temperature. (Pun intended.) It's conservation of energy. Whatever heat goes up the stack doesn't go into the heated space, A high efficiency furnace or boiler sends it's combustion products out at less than 200 F, but even an "efficient" steam boiler might have a stack temperature of 300 F or more.

According to steam character, steam boiler can be divided into saturated steam boiler and superheated steam boiler. In a boiler, energy from the fuel is transfered to liquid water in order to create steam. At first, cold water gets warmer and receives energy in the form of “sensible heat”, right until the boiling point.
