Palm waste as alternative fuel for cement plant

Cement industries usually with high production capacities utilize a lot of heat energy to produce cement in the kiln in which toxic materials such as dioxin can be discomposed at a high temperature of about 1450°C. Conventional cement plants depend on coal to provide the heat energy needed. Since clinker is used as the raw material for the production of cement, no secondary waste material will be generated. In order to mitigate environmental issues like carbon emission reduction, palm biomass can be used to replace coal. This may qualify for carbon credit under the Clean Development Mechanism (CDM). However, recycling of waste as an alternative fuel will increase the volume of volatile components, particularly chlorine (Cl), sulphur (S), and alkaline substances (Na, K) causing pre-heater deposits and cyclone clogging in the cement clinker burning system. This will lead to the development and installation of chlorine by-pass and anti-sulphur coating system into the clinker preheater plant.
