    These methods may be in the way of deflectors, or baffles, to hold back the gas or create more turbulence. Another option is to use an economizer on the boiler, to capture the heat before it exits the stack. The most effective method is by having a boiler with multiple gas passes, in the combustion area.Learn More

  • Summary of Boiler and Process Heater Test …

    The boiler is better able to respond to large loads as the 'low fire' position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on 'low fire', it can immediately respond by increasing the firing rate to 'high fire', for example the purge cycle can be omitted.Learn More
