Plant Engineering | A quick guide to condensate recovery

Oct 28 2013 · Maximizing boiler output: Colder boiler feedwater will reduce the steam rate of the boiler. The lower the feedwater temperature the more heat and thus fuel needed to heat the water thereby leaving less heat to raise steam. Boiler feedwater quality: Condensate is distilled water which contains almost no total dissolved solids (TDS). Boilers ...

Introduction to Condensate Recovery | TLV - A Steam ...

Lower Water-related Expenses. As long as any impurities picked up during condensate transport are removed condensate can be reused as boiler feedwater reducing water supply and treatment costs as well as costs associated with cold water used to lower condensate temperatures

Introduction to Condensate Recovery | Spirax Sarco

Each kilogram of condensate not returned to the boiler feedtank must be replaced by 1 kg of cold make-up water (10°C) that must be heated to the condensate temperature of 90°C. (T = 80°C). Calculate the heat required to increase the temperature of 1 kg of cold make-up water by 80°C by using Equation 2.1.4.

May 04 2021 · Also the calculation uses only one boiler efficiency. Steam is being generated @ 100 psig and is being returned to a deaerator tank operating @ 10 psig. Fuel cost is $9.50/MMBtu ($/GJ) and boiler efficiency is 80%. S C = S C = $11.67 per 1000 lbs. 2. IMPROVING THE CALCULATION OF THE UNLOADED COST OF STEAM 2.1. Condensate Return to the Boiler ...

Mar 17 2015 · 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.

Water Recycle/Reuse Possibilities: Power Plant Boiler and ...

It is expressed by the equation M = R[KB + KR] where: M = makeup water flow rate in Kg/hr R = steam production rate in Kg/hr KD = blowdown rate expressed as a fraction D of steam production KD = condensate/steam leakage rate expressed K as a fraction of steam production 9
