Explain the types of tube failure that may occur innthe initial stage of boiler operation till stabilization?
During the initial stage of boiler operation, until the system reaches a stable operational phase, several types of tube failures can occur. These failures are often related to start-up conditions, improper handling, design flaws, or material weaknesses. The initial period of boiler operation is critical, as it involves high thermalRead More
Analysis of the statement on mill outlet temperature:
Points in favor of higher mill outlet temperature (up to 100 – VM): Risks and precautions for high mill outlet temperature: Overall recommendation: Running the mill at a higher outlet temperature, up to the recommended limit (100 – VM), can offer several benefits in terms of combustion efficiency, mill performance, and clinker reduction. However, careful monitoringRead More
How Flue Gas Exit Temperature Impacts Coal Mill Performance
The efficiency of a coal-fired power plant hinges on optimal heat transfer throughout the system. One crucial factor in this equation is the flue gas exit temperature, which indirectly affects the performance of the coal mill. Let’s delve into the how and why: 1. Insulating Invaders: Scaling and Soot DepositsRead More
FSSS (Furnace Safeguard Supervisory System)
FSSS LOGIC SYSTEM BOILER START- UP SEQUENCE The boiler can be placed in service, initially or after a “Master Fuel Trip,” in the following sequence through FSSS. Furnace Purge:- Before any fuel firing can takes place, initially or following a boiler trip, a satisfactory “Purge Cycle” must be completed. Initially,Read More
Causing of fluctuations in working pressure of a boiler
What are the causes of fluctuations in working pressure of a boiler? (AP_BOE_2010_P_1) 1. **Fluctuation in load:** This is a common cause of boiler pressure fluctuations. When the demand for steam increases, the boiler pressure will drop as the boiler tries to generate more steam. Conversely, when the demand forRead More
