If you were to pressurize the part containing solid fuel it becomes "combustor" in pic related. Compressing cold input air and solid fuel might be worth the trouble: vessels will be smaller, catalysts more active and more importantly: cooling the syngas won't increase efficiency by reducing compressor work. If you're going to take input heat away from the gas turbine, why not take it from higher temperature gas? If you stick with low pressure syngas, the steam turbine might be too small and complicated to bother with: that is you get <1 kW from the steam turbine and 10kW from the gas turbine and you can't run the gas turbine if the steam turbine needs repair.
