Discuss practical improvements for performance and reliability.

This is the most common reactionary operation practice whenever the stack temperature is found on the higher side by most. Sometimes the LRSBs get stuck, which leads to major erosion of the SH/ RH tubes. We invite all to...

A pinhole leakage is quite often seen from the weld joints of the Economizer. Faulty welding is usually considered to be the root cause. But is that the only root cause? Then why it is occurring in the Economizer outlet...

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...

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...

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...

Combustion optimization is perhaps the most important action that is required to improve performance of a boiler, more so, in a solid fuel fired boiler. Frequently changing load and fuel quality demand frequent adjustmen...

Increased SH/ RH spray indicates possibility of overheating of the SH/ RH metallurgies. In order to reduce the spray quantity, the wall blowers are operated frequently, sometimes in every shift at many boiler systems. Fr...

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...
