Abstract: A process and apparatus are described for generating electrical energy using grains or other renewable biomass as the fuel, and for producing fertilizer to grow subsequent crops. In the process, a biomass material is incinerated in a firebox of a boiler to power a first turbine to create electricity. An excess air flow is introduced into the firebox to increase NOx production. The oxidation area of the boiler is operated at a temperature exceeding about 2,000° F., and the flue gases are maintained in the high temperature environment for an increased residence time to increase NOx production. The flyash from the incinerated biomass is filtered from the flue gases exhausted from the boiler. The NOx is removed from the filtered flue gases and used to produce a nitrogen fertilizer. The nitrogen fertilizer is blended with the flyash to form a balanced fertilizer product which allows sustainable production of the biomass material.
