Module Learning Outcome
On successful completion of this module the learner will be able to:
# Module Learning Outcome Description
MLO1 Appraise the role of incineration in waste management and energy generation and be able to describe the incineration and heat recovery process
MLO2 Examine the potential pollutants of air, land and water that are associated with incineration and recognise the necessity for pollution prevention and control requirements
MLO3 Compare the types of biomass fuel suitable for use with reciprocating engines and explain the modifications needed to enable the reciprocating engine to utilise biomass fuels effectively
MLO4 Critically evaluate various complete processes for the conversion of biomass to electricity or CHP and give examples of actual plants
MLO5 Assess the financial/economic performance of a biomass-to-energy plant
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named DkIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
