Case study - Bespoke Solutions
PROJECT
450kg/hr animal remains incineration project in accordance with PG5/3, The Secretary of State’s Guidance Note for the incineration of animal remains under 10 tonnes per day
Lincolnshire, UK
PROJECT DESCRIPTION
The purpose of the plant was to provide an incineration solution which complimented the clients livestock slaughter facility and reduced their reliance on the rendering business. The system would be required to operate 24/7. That, combined with the waste type to be incin-erated meant that the solution had to be of rotary primary chamber design. In order to re-duce the manpower associated with 24/7 operation the incinerator was complimented by a waste storage, processing and delivery system along with automatic de-ashing.

The solution had to be a complete waste processing facility capable of operating 24/7. Therefore, an integrated bunkering system with shredder, transfer conveyor, delivery pump and automatic de-ashing was a must.
The process reduces the mass of the waste by 95-96% and leaves a white, calcined ash containing less than 3% carbon.
The rotary primary chamber sits on a slight incline down towards the vertical secondary chamber. The rotation of the chamber con-tinuously agitates the waste. Also, combined with the slight incline, drives the waste along the chamber as the incineration process advances. At the entrance to the secondary chamber, the mass waste will have been reduced by 95-96% leaving a white calcinated ash of less than 3% carbon.
The bespoke vertical secondary chamber was designed with the aid of computational fluid dynamics for ultimate efficiency re-sulting in a compact unit without compromising on residence time.
High grade cast refractory on the hot face of the chambers en-sures the longevity of the incinerator with minimal maintenance.
Composite insulation ensures low cold-face temperatures and minimal heat loss to the atmosphere offering best possible fuel consumption.
PROJECT MANAGEMENT AND THE FUTURE
The system was handed over to the client on schedule and to specification. The client has ex-perienced many successful years of operation and has returned to Matthews Environmental Solutions with further equipment requirements.
Matthews Environmental Solutions have continued to provide servicing and maintenance sup-port to the client since installation of this, and other machines, and look forward to being ap-proached again in the future with more challenges.
