FAQ

What types of fuel can be used in biofuel-fired boiler plants and power stations?

Biofuel-fired boiler plants and power stations are equipped for combustion of chipped wood mixed with bark, sawdust, peat, straw, felling waste, lignin, etc.

 

What is an average efficiency of the boiler plant?

In the absence of flue gas condensing economizer, average efficiency of the plant is approximately 87%; after installation of flue gas condensing economiser, depending on fuel moisture and temperature of the returning heating water, plant’s efficiency could increase to an average of 110%.

 

Are biofuel-fired boiler plants environment friendly?

Biofuel-fired boiler plants, like other industrial facilities, emit CO2, CO, NOx, SO2 and solid particles into the atmosphere, however boiler plants build by Axis Industries comply with all applicable environmental requirements.

 

What is a flue gas condensing economizer?

A flue gas condensing economizer is one of the main installations of a modern boiler plant, where flue gas is cooled down to below the dew point, therefore when high moisture fuel is combusted, energy used to evaporate the moisture is regenerated in this installation by condensing water vapours present in flue gas. This allows increasing efficiency of the boiler plant by 20-35%.

 

How can I evaluate fuel consumption?

The most accurate way to measure fuel consumption is by installing a 60 ton weighbridge, keeping records of fuel supplied to the boiler plant and performing quality analysis of fuel samples in a laboratory.

 

How is efficiency of the boiler plant calculated?

Efficiency of the boiler plant is calculated by summing up all profitable energy output (electricity and thermal energy generated in the turbine condenser and flue gas condensing economizer) and dividing it by the fuel energy consumption.
