OVENS , SPRAYBOOTHS & PROCESS HEATING
Burn off ovens offer effective process to remove plastic , paint coatings or contaminants
Burn off ovens ( also commonly known as pyrolysis ovens or burnout ovens ) offer an extremely effective process for the removal of plastic or paint coatings and contaminants from process machinery and components . This burns off the unwanted residue and preserves the original machinery part with minimal damage , offering prolonged lifetime and multiple usage . Our burn off / burnout ovens are custom built here at Longworth and can therefore house and clean a wide range of items and sizes .
How does a burn-off oven work ?
Burn-off 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 .
Longworth burn off 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 .
Benefits
Our skilled and responsive team of engineers will ensure that your pyrolysis oven is maintained to perform at optimum efficiency .
The robust design and construction of our burn off ovens means they offer years of reliable performance even in the harshest industrial conditions .
Built using 20 years of knowledge and experience gained from the cleaning of components from many different production processes and industrial cleaning environments .
How Does Pyrolysis Work ?
Burn off processing involves heating a contaminated component at a controlled temperature in a low oxygen environment . This has the effect of vaporising the volatile constituents of the contaminations .
We also sell our burn ovens for customers to use within their own facility , and we only ever sell the same specification ovens that we use ourselves for on-site processing , giving peace of mind that the same results can be achieved .
Benefits
Less damaging than traditional cleaning processes
No expensive chemical disposal costs
Custom designed PLC control including ramped temperature control
