Change of the fuel base of the grate hot water boiler with output of 50 MWt from coal to natural gas

The aim of this thesis is change of the base of the grate hot water boiler wit output of 50 MWt from coal to natur gas. The supply water temperature is 70°C and the pressure 2MPa. The first part of thesis, the coal consumption for the current state of the boiler is calculated. For a natur gas is calculated stoichiometric calculation and then thermal calculation performed. This thesis also assesses the type of boiler operation after changing the fuel base
