Read MoreA 440 MW power generating unit, with a subcritical once-through Benson type boiler, is considered in this study. The nominal steam mass rate of the boiler is about 390 kg/s (1405 ton/h), where the main superheated steam temperature is 535 C and the output

Read More2016/7/28 · 4.) maximum steam generating capacity in pounds of tonnes per hours.This term is the most informative and easiest to understand if it refers to steam properties the boiler is designed for. (Large boiler capacities are often given in lbs or tonnes of steam evaporated per hour under specified steam conditions, for smaller boilers capacity is given in smaller units.)

Read More2015/3/17 · 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.

The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment. A fire-grate is located at the fire-box base as well as coal is fired-up on the firebox.
