Abstract—The technology to facilitate liquid sewage sludge
disposal with minimum energy consumption for primary
drying before incineration in a furnace is proposed. The
possibility to use an industrial boiler was studied
experimentally. The experimental test-rig was developed at
Technion (Israel Institute of Technology) and the proposed
concept was demonstrated successfully. Sewage sludge from
municipal wastewater plants with a moisture content of up to
95-99% combined with pulverized coal and liquid light fuel at
various ratios was burnt. Sewage sludge co-combustion leads to
an insignificant temperature reduction inside the furnace, and
is able to provide stable combustion with low NOx and CO
emissions.
Index Terms—Component, formatting, sewage sludge, liquid,
incineration.
