Discuss practical improvements for performance and reliability.

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...

At many plants the CBD is operated in the fashion any common man takes a paracetamol pill whenever his body temperature exceeds 98.6 oF. If boiler water chemical parameter exceeds the limit, it tells us something is wron...

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...

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...

The loss of un-burnt carbon with Fly ash and Bottom ash of any solid fuelled boilers is undesirable as it leads to huge wastage of fuel and thus revenue loss. Un-burnt in the fly ash in particular should be critically co...
