Discuss practical improvements for performance and reliability.

This type of failure is the most devastating amongst all. While the primary cause is failure of water treatment, overheating also contributes significantly to the cause. Careful monitoring of the parameters and timely co...

With increased number of start-up required by the present day’s power boilers, Thermal fatigue cracks in the attachment welding can be a common problem. Systematic inspection and maintenance practices can reduce these pr...

Erosion failure in economizer tubes is quite common with boilers using Indian coal. However, with some, the frequency of such failures can be significantly high. We invite all to share their practices and strategies to m...

The metallurgies used in these tubes are highly susceptible to overheating failures and thus highly sensitive to temperature excursions. Frequently changing load, increased number of start-ups, fast ramp-up coupled with...

There are more numbers of oil fired packaged boilers operating in our country than any other types. Improper fuel oil treatment leading to excessive soot formation is experienced in a number of such boilers. This not onl...

A selected discussion topic on a common plant O&M issue This is becoming quite a big challenge for a number of CFBC boilers, particularly with the new stringent emission limits imposed by the PCB’s. Ineffective in-bed su...

This is one area where most organizations take lots of initiatives. Introducing VFD for flow control, replacement of under loaded auxiliary equipment, trimming of impellers, etc. are quite common. However, sometimes a pa...

Slagging and fouling can make the life of the PF boiler O&M personnel really difficult at times. This often leads to saturation of ID Fan capacity and creates a highly unsafe condition in the furnace. We invite all commu...

Another hazard of very low load operation coupled with use of low VM coal. Proper combustion tuning at technical minimum load has become essential with all coal based power plant boilers. Please share your experience in...

This is becoming a generic problem with most coal fired power station these days with the percentage VM getting lower and lower in the indigenous coal. We invite all to share their practices and strategies to meet this c...
