ignition, bringing the boiler up to normal operating conditions, and preparing and pressurizing the steam headers. Ignition Although boilers have many different specific ignition systems, they all follow the same basic sequence of steps: 1. Pre-purge of the furnace. 2. Reduction of air flow for stable ignition. 3. Pilot burner ignition 4.

Prior to equipment commissioning and start-up, operators are trained on the new operating procedures. TXU Energy has several plants that were originally designed to be fueled with Texas lignite in
The efficiency of the boiler; All the gas boilers we install are A-rated and are over 90% efficient, this makes them much cheaper to run. If you go from an old back boiler to a new A-rated condensing gas boiler, the savings on your energy bill can be up to 40%. We have illustrated the cost savings available by installing a new gas boiler, below

Both the equipment and operating procedures are key factors in managing the cost of cycling. COAL informed decisions about using biomass cofiring in existing coal-fired boilers decades. Cofiring is a standard. Appendix D: Federal Life-Cycle Costing Procedures and BLCC.
Heating Equipment Guidelines . The following operating procedures for heating equipment include guidelines for both boilers and electric heating: Boilers: General . Inspect boilers for scale deposits. Accumulation of sediment or boiler compounds on waterside surfaces must be removed.

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng, 2004 ).
