Two-stage fuel oxidation and comparison of water catalytic boilers with fluidised bed and fixed layer

The new method of decreasing NO_x emissions in catalytic boilers consisting of two-stage (two-chamber) fuel oxidation is presented in the following paper. The corresponding plant and parameters in it are described. The second part of article contains the comparison of technical and economic characteristics of Russian and foreign hot water catalytic boilers with fluidised bed and fixed layer.

Keywords: catalytic boilers, NO_x emissions, two-chamber fuel oxidation, hot water boilers, fluidised bed, fixed layer, nitrogen oxides, pollution emission
