Objective

To produce information on emissions, reactivity and alkali release of pulverized solid fuels burning at high temperature and pressure for possible construction of full scale boilers in the future

The work program includes studies of reactivity and emissions of pulverized solid fuels burning at high temperature and pressure. The results obtained with different fuels will be introduced in a model in order to predict the reactivity in the pressurized devices constructed.

Four group of tasks are included in the work program.

1) Basic data on reactivity of pulverized fuels (mainly coal) as a function of pressure will be determined at a laboratory scale; simultaneously the emissions of gaseous products will be characterised as a function of temperature, pressure and gaseous environment.

2) The results obtained will be used to design the structure of a pressurized entrained flow reactor allowing visual observation of the flame of the pulverized solid fuels. Gaseous species evolution are continuously followed through FTIR spectrometer and continuous analyzers. The results obtained are compared with those obtained in the high pressure thermal balance device.

3) Development of a method for measuring the concentration of gaseous alkalis in the flue gas of a pressurized coal burner. The type of coal, its rank, particle size, mineral content and 02 partial pressure will be varied.

4) The data obtained through task 1 and task 2 will be introduced in a model which calculates the ignition delay, burning time and surface temperature of small particles under pressure. This model will also tentatively predict the amount of gaseous alkali species measured in task 3.
