| description | This paper presents an experimental study on co-combustion of two types of rice husk with substantially different
properties in a fluidized-bed combustor using fuel staging for lowering NO emission. Rice husk pellets were burned as a base (or
primary) fuel, whereas moisturized rice husk was injected downstream from the primary combustion zone as a secondary fuel.
The experiments were conducted at 200 kWth heat input to this reactor with a bottom air supply, while the energy fraction of the
secondary fuel in the total heat input ranged from 0 to 0.25, and excess air was within 2080% for each co-firing option. The
study revealed significant effects of the operating parameters on combustion and emission performance of the combustor.
Compared to burning of the base fuel, a nearly 40% NO emission reduction is achievable with fuel staging, while controlling the
CO and CxHy emissions from the combustor to acceptable levels. However, fuel staging causes some deterioration in the
combustion efficiency. |
