Blowdown in Boiler | Boiler Blowdown Calculation Formula

Certain key information is required for each boiler re- placement job in order to calculate the heat loss, select the proper boiler and determine the selling price. Fig- ure 1 is a Job Survey Form (part of a Weil-McLain Boiler Replacement Worksheet) to aid in recording the re- quired information. It will serve as a checklist of the ba-

A scotch marine boiler has a furnace volume of 45.5 cu. ft. if 3825.2 cu. ft. of natural gas is burned per hour and each contains 1100 Btu, what is the rate of combustion? RC = H / (Vf * t) Return Condensate Percentage in Feedwater

Mar 17, 2015 · Calculation Details Step 1: Determine Properties of Steam Produced Using the Steam Property Calculator, properties are determined using Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and Step 3: Determine Blowdown Properties

Nov 24, 2016 · There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) Boiler Efficiency by Indirect Method: Where the efficiency is the difference between the losses and the energy input.

Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour.
