Abstract

A method of metering underfire air for increasing efficiency and reducing particulate emissions from wood-fire, spreader-stoker boilers is disclosed. A portion of the combustion air, approximately one pound of air per pound of wood, is fed through the grate into the fuel bed, while the remainder of the combustion air is distributed above the fuel in the furnace, and the fuel bed is maintained at a depth sufficient to consume all oxygen admitted under fire and to insure a continuous layer of fresh fuel thereover to entrap charred particles inside the fuel bed.

Combustion characteristics of hogged Douglas-fir bark in spreader stoker boilers

Book Junge, D

Initial results are summarized of studies of combustion characteristics of Douglas-fir bark (hogged fuel) as burned in a spreader stoker experimental test facility. Attempts were made to determine combustion characteristics for fuels burned in controlled conditions. Independent variables include wood size and MC, underfire/overfire air ratios, and fuel-to-air ratios. The work is presently under way at Oregon State University in a water wall spreader-stoker with a 10 ft/sup 2/ grate.
A study of factors influencing NO/sub x/ emissions from spreader-stoker wood-residue fired boilers

Conference Dallons, V; Hoy, D - Proc., Annu. Meet., Air Pollut. Control Assoc.; (United States)

Parameters influencing NO/sub x/ emission rates from spreader-stoker, wood-residue fired, industrial boilers were investigated at 4 units. The major operating conditions affecting wood-residue fired boiler NO/sub x/ emission were excess air, fuel nitrogen content, the amount of air supplied through the grate, and the fuel moisture content. Excess air use had the greatest effect on NO/sub x/ emissions from wood-residue fired boilers. NO/sub x/ emissions were proportional to the square-root of the flue gas oxygen concentrations. The minimum practical excess air use was limited by the production of high CO and smoke emissions that developed at low excess air use.more »« less
Improved combustion of wood waste in industrial boilers. Technology applications manual; technology transfer

Technical Report

To provide information on optimum design and operation of existing wood residue fired spreader-stoker boilers, research was conducted on a pilot-scale spreader-stoker boiler. Wood waste combustion was investigated as a function of fuel size, moisture content, species, air:fuel ratios, and type of equipment used. Data collected from the test facility show that distribution of combustion air to the combustion chamber is critical to efficient operation of boilers. The results indicate that more complete combustion of wood residue is possible when excess air is reduced significantly below commonly used levels, the underfire air supply is reduced, and overfire air is distributedmore »« less
