The Burn-Off
Longworth's Flagship Oven
Our burn off ovens (also referred to as burnout ovens, Jig ovens, pyrolysis ovens) are constructed to exacting standards to suit the particular requirements of individual clients. To achieve the precise control our customers expect, each oven features a number of distinct burn-off or pyrolysis temperature profile settings. These profiles can be used to gradually break down the contamination whilst preventing the overheating of the component being processed.
Although our standard selection includes several models in various sizes – on the rare occasions that our selection doesn’t offer something to suit your requirements, we will design an oven to address your specific needs.
FEATURES
- Several models which come in various sizes, bespoke options available to suit requirement
- Incorporates PLC control, Touch screen HMI and on screen fault finding facility
- Oven interiors can be lined in stainless steel to avoid damage to internal insulation sustained via everyday knocks and scrapes
- Online oven maintenance option allows remote maintenance and fault finding from engineers in our Blackburn (UK) office
- Hydrogen ready combustion burners
FUEL SUPPLY
Natural Gas, LPG, Light Oil, Kerosene
How does it work ?
Burn-off or burnout ovens use a process known as pyrolysis. They remove or break down organic materials that have adhered to metal parts. This works by heating the parts in a reduced oxygen atmosphere where a reaction takes place and reduces the contaminant to a residue that is richer in carbon. Any emissions that are given off during this process are put through an afterburner that heats these gasses to 850°C for a minimum of half a second. By heating these gasses to such a temperature turns them into H2O and CO2.
