Ace Waste’s High Temperature Incineration (HTI) plant provides the ability of utilising inherent heat energy in various regulated and prescribed industrial wastes to assist with combustion and promote Waste to Energy initiatives.
The Plastic content in Clinical and Related waste is approximately 30% and as a result is an excellent alternate source of energy.
In fact plastic has the same calorific value (energy) as natural gas at 46 MJ/Kg.
The Ace Waste incinerator requires 32 GJ/Hr of natural gas to maintain combustion, however the clinical and related waste stream has enough energy, primarily due to the high (30%) plastic content to maintain combustion conditions with minimal requirement for natural gas. The rated calorific value of clinical waste is 28 MJ/Kg and by comparison coal has around 32 MJ/kg energy.
In essence this means that clinical waste represents between 90 and 95% of the energy required to operate the incinerator.
This means that not only is the clinical waste being permanently destroyed but the inherent energy in the waste is providing over 90% of the heat energy required to maintain combustion.
Once the incinerator is operational at 1,000°C, the only inputs are clinical waste and combustion air.
Auxiliary fuel in the form of natural gas is only required to provide the pilot flame in the secondary chamber.
Waste to Energy Strategy
Apart from providing the vital energy to maintain combustion, the incineration process generates significant heat energy and this is able to be harnessed to power the various fans and motors of the incinerator plant and equipment.
Ace Waste has recently purchased a 700 KVA diesel powered generator of sufficient capacity to power the incinerator as well as other on site needs, however this equipment uses diesel fuel which comes at a cost.
We are currently assessing alternative technologies which have the advantage of harnessing some of the surplus heat energy and which in turn can operate a steam boiler/turbine/condenser system.
Resultant power will be sufficient to operate the main fan motors required to operate the incinerator plant and fulfil our aim of being self-sufficient when it comes to power requirements.
In summary, Ace waste has commenced its WTE strategy and intends to maintain current operating conditions utilising the existing waste volumes to realise and capitalise on this important initiative.
High Temperature Incineration (HTI) has several advantages over alternate Treatment/Landfilling Options.
