Boilers | Energy Control Steam and Hot Water Boiler

A steam accumulator is a pressure vessel (or tank) with internals and controls, that can reduce the fuel consumption, maintenance costs and increase the service life of your boiler by stabilizing the steam draw conditions, but it cannot make up for shortcomings in total boiler capacity. The accumulator acts as a flywheel or capacitor, storing energy for short periods until the process requires it.

5 Factors Killing Your Industrial Boiler Efficiency amp;

1. Excess Air Effect on Industrial Boiler Efficiency. All combustion burners require some degree of excess air. Excess air is defined as the amount of air in a combustion process greater than the amount theoretically required for complete oxidation. To ensure complete combustion of the fuel used, combustion chambers are supplied with excess air.

Boiler Efficiency Calculation: a complete guide

To obtain high combustion efficiency, burner and boiler combustion chamber must be designed as optimal as possible. On the other hand differences in the use of fuels also affect the efficiency of combustion. It is known that liquid fuel and gas (LNG and HSD) produce higher combustion efficiency than solid fuels such as coal.

Improving Boiler Efficiency - Energy Depot

Efficiency Improvement - Up to 2 percentage points. Turbulators are metal baffles inserted into fire tube boilers to increase the heat transfer by increasing the surface area and slowing down the combustion gases. Soot blowers use steam or compressed air to help keep the fire-side surface of solid fuel or oil fired boilers clean.

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 (gt;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.
