Abstract
A solid biomass-to-energy combustion method includes introducing an oxygen containing gas into a combustion chamber of a suspension furnace to form a flow of gas through the combustion chamber; injecting a particulate solid biomass fuel into the combustion chamber through a port in the furnace wall and into the gas flow, and combusting the particulate solid biomass fuel in the gas flow to form a flame in the gas flow.
Claims34
A method of preparing solid biomass fuel for a solid biomass-to-energy combustion system, comprising:
- providing solid biomass fuel;
- reducing the solid biomass fuel into solid biomass particles having a particle size distribution such that substantially 100% by weight of the solid biomass particles pass through a sieve having 0.125 inch diameter holes.
A solid biomass fuel for a solid biomass-to-energy combustion system, comprising:
- particles of wood and diverse biomass with less than 5% water by weight, the particles of wood and diverse biomass having a particle size distribution such that substantially 100% by weight of the wood and diverse biomass particles pass through a sieve having 0.125 inch diameter holes.
A solid biomass-to-energy combustion method, comprising:
- introducing an oxygen containing gas into a combustion chamber of a suspension furnace to form a flow of gas through the combustion chamber, the combustion chamber being defined by a furnace wall;
- injecting a particulate solid biomass fuel into the combustion chamber through a port in the furnace wall and into the gas flow;
- and
- combusting the particulate solid biomass fuel in the gas flow to form a flame in the gas flow, the particulate solid biomass fuel comprising less than 5% water by weight and having a particle size distribution such that substantially 100% by weight of the particulate solid biomass fuel pass through a sieve having 0.125 in diameter holes, so that the particulate solid biomass fuel particles are substantially completely combusted within the combustion chamber while suspended in the gas flow and are not combusted at the furnace wall.
A solid biomass-to-energy combustion method, comprising:
- introducing an oxygen containing gas into a combustion chamber of a fossil fuel suspension furnace to form a flow of gas through the combustion chamber, the combustion chamber being defined by a furnace wall;
- injecting a particulate solid biomass fuel into the combustion chamber through a set of ports in the furnace wall and into the gas flow, the set of ports also being spaced about the combustion chamber;
- and
- combusting the particulate solid biomass fuel in the gas flow to form a flame in the gas flow, the particulate solid biomass fuel comprising less than 5% water by weight and having a particle size distribution such that substantially 100% by weight of the particulate solid biomass fuel particles pass through a sieve having 0.125 inch diameter holes, so that the particulate solid biomass fuel particles are substantially completely combusted within the combustion chamber while suspended in the gas flow and are not combusted at the furnace wall.
