Purpose built incinerators are available for most applications ranging from hazardous/hospital waste, cremators and for recovery of drums and cans for reconditioning purposes.

The units are typically conventional refractory lined and may be employed for either continuous use or batch processing. The PTE range offers models with throughputs from 30 kg/hr up to 1000 kg/hr. The smaller capacity models are a packaged design, ideal for quick easy installation and in most cases can be shipped in a standard container.

PTE products have been designed and developed for the safe destruction or treatment of specific types of waste. To assist you in determining the type best suited to your application we describe the particular design points and uses of each range.

PTE design and manufacture incineration equipment such as:

• Automatic combustion rate control ensures that an excessive burning rate is immediately and automatically reduced. Conversely when the burning rate is low, more rapid combustion is induced. This control is achieved by variations in gas flows and pressures and does not incorporate any moving or wearing parts.
• Automatic temperature controls regulate the auxiliary heat supplied by both primary and secondary burners. This ensures longer refractory life and maximum fuel saving.
• Automatic fan controls keep the burner fans running after shutdown. They switch off automatically once the incinerator has cooled off sufficiently. This results in longer life for the burner draught tubes, nozzles, diffusers and flame detectors.
• Automatic air control completely eliminates the necessity for manual operation of air dampers. Balanced quantities of primary and secondary air are constantly varied to suit changing combustion conditions. No moving parts are involved.
• Preheated combustion air which saves fuel is drawn into the combustion chambers from an ante-chamber where heat is collected from the base of the chimney stack.
• Implified electric control panels on standard PTE models are designed for operation by unskilled labour. A single, lockable push-button actuates the starting of all burners, fans, ignition transformers, solenoid valves and control instruments in the correct sequence. Similarly the shut down is actuated by a single push-button.
• Door operated draught reducer automatically reduces the chimney draught while the loading is open and shuts off the normal air supplies. The resulting reduction in the amount of cold air drawn in through the loading door reduces fly-ash entrainment and thermal shock on the refractory, with resultant longer refractory life.
• Explosion relief safety doors swing open in the unlikely event of an explosion. The sliding loading door swings out at the bottom and the blast is directed downwards.
• High alumina monolithic refractory linings withstand temperatures in excess of 1 500°C and are specially selected to give maximum durability under conditions of sudden and extreme temperature change (thermal shock). The carefully controlled bake-out which is part of the service supplied by PTE ensures optimum linings with a long life expectancy.
• High quality insulation around the entire incinerator ensures low surface temperatures and minimum fuel consumption.
• Dry type smoke and fly ash elimination which has proved completely effective, also ensures dry corrosion- free chimney stacks and hot dry gasses that rise straight off the top of the chimney. (No wet, dragging plume.)
• Bold, easy to read indicators take the form of a rugged draught indicator, large pilot lamps and a temperature gauge.
• Large sliding loading door are at the right height and angle for easy loading or raking.
• Smooth outer casing free of obstructions is easy to keep clean. All the rolled steel sections used to brace the incinerator are inside the casing, which is at least 4,5mm thick on all units.
• PTE offer country-wide service facilities.
