Pump efficiency can not be taken as given.
The boiler maximum continuous rating (MCR) refers to the maximum amount of steam or hot water that a boiler can produce continuously under standard operating conditions. It is typically expressed in terms of mass flow rate, such as kilograms per hour (kg/h) or pounds per hour (lb/h). The MCR is important for determining the boiler's capacity to meet demand and is a critical factor in system design and efficiency. Understanding the MCR helps ensure that the boiler operates within its safe and efficient limits.
An IK on a boiler is a Soot Blow. It is mounted on the sidewall of a boiler furnace and cleans the internal boiler parts with high pressure.
ATMOSPHERIC BOILERa boiler on which combustion air/flue gases are drawn through the boiler without a fan.(Taken directly from the Crown Boiler Co. web-site.)
Boiler can be classified as below
boiler efficiency is how much water is converting to steam.
Boiler efficiency is calculated by determining the steam value per hour and dividing it by the amount of fuel which is consumed per hour. By doing this one can determine the efficiency of a boiler.
Boiler power is not determined in megawatts. A boiler horsepower is determined as 33000 btus. That is equivalent to 34.5 pounds of steam from and at 212 F. Conversion of boiler conditions (factor of evaporation) output and horsepower to atmospheric steam conditions is the norm for determining boiler horsepower. The ASME code contains several methods for determining boiler horsepower. Megawatts are a determination of turbine-generator output.

we can increase boiler efficiency by recovering the heat which is being carried by flue gases.by incorporating different things like Economizer, Air pre-heater , Super-heater and feed-water heater, we can there ll be notable increase in efficiency of boiler.
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
The economizer is used to raise feedwater temperature up to nearly the temperature of the boiler to avoid thermal shock and improve the boiler's efficiency. Every 11 degrees Fahrenheit increase in feedwater temperature yields a 1% increase in boiler efficiency.

There are many factors. First of all, there is the temperature of the water. Next, the is the volume of water. Next there is the amount of pressure gradually built up in the boiler. Next you have the amount and speed at which heat is transferred to the water.
An economizer is used to heat boiler feedwater up closer to the temperature of the boiler water, using heat from the boiler exhaust gases, heat that would otherwise be wasted. The main reason is to improve the efficiency of the boiler. For every 44 degree F drop in exhaust gas temp. there is an 11 F rise in feedwater temperature and a 1% gain in boiler efficiency.
