What Causes Clinkers in Coal Fired Boilers? Hunker

Clinkers have been a recurring problem in all coal-fired boilers for as long as humans have operated coal boilers. Small clinkers can fuse together to form large ones that can physically damage boilers. Some companies are offering chemical combustion enhancers to be added to coal that they claim will virtually eliminate clinker

Evaluation of ash melting behavior in pulverized coal

In pulverized coal-fired boilers, the generation of high-strength clinkers due to slagging has been one of the most crucial problems . Because high-strength clinkers tend to grow larger than weak ones, they might deteriorate heat exchanges or damage hoppers by dropping off from upper parts, which might cause unplanned shutdowns of power plants.

How to Destroy a Boiler -- Part 1

Due to the critical need for water, modern boilers are equipped with automatic low-water trip switches. Some older boilers may not have these relatively inexpensive devices. If your boilers do not have low-water trips, run, don't walk, to the phone and initiate their installation. You have an accident and expensive repairs waiting to happen.

Boiler Combustion CleanBoiler.org

As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.
