PRE-TREATMENT, SURFACE PREPARATION, DEGREASING & CLEANING WE ARE AT SURFACE WORLD LIVE 2020 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 96 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. 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. Benefi ts Less damaging than traditional cleaning processes 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.
