Steam Boiler Ducting Calculations Worksheet

CHAPTER 3 COMBUSTION CALCULATION

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.

Procedures for Calculating Natural Ventilation Airflow

Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is ; of the fuel burned, 90% reacts to form CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC.

Ductwork sizing, calculation and design for efficiency

Steam Boiler fires. Water boils in boiler, creating steam. Surface level rises slightly because the steam bubbles displace water. Pressure pushes air out through Main and Radiator vents. Water begins to back up in the return riser because flow causes pressure drop in piping. So pressure is lower at end of piping than at boiler.
