Boiler Efficiency | How to balance steam loads efficiently

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

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.

May 01, 2016 · In duration of 8 a.m–12 p.m, electrical demand is lower than heat demand in this period. In the time, electricity price is more than gas price. Therefore, the hub would rather purchase gas for CHP to provide electrical and heat demands simultaneously. The rest of heat demands are supplied by purchasing gas for boiler to supply heat demands.

Different Types of Heating Systems for Your House

May 29, 2019 · A boiler is a special-purpose water heater that provides centralized heating system — transferring natural, comfortable heat into a house. It works much like a furnace except, instead of using fuel to heat the air, it uses fuel to heat water. The boilers utilize natural gas, electricity, propane, or oil.

Boiler control - Plant Services

Feb 25, 2004 · Boiler drum-level control is critical. Too low a level may expose boiler tubes, which overheats and damages them. Too high a level may interfere with separating moisture from steam, which reduces boiler efficiency and carries moisture into the process or turbine. The drum-level controller maintains the level at constant steam load.
