Industrial Gas Appliances are classified as Type B. This encompasses all gas appliances that are not on the prescribed list and consume gas at greater than 10MJ/hr. There are a wide range of appliances in this category used by industry, Coffee Roasters, Truck Spray booths, small stand-by generators to power stations, are just a sample. It is generally necessary to provide detailed information on these appliances, referred to as a technical submission, this enables the basic appliance concept to be assessed and design approved prior to the appliance being prepared for installation. Once installed there is a rigorous testing regime prior to approval.
All Type B appliances require individual, specific approval by an inspector.
Type B Approval Process
Type B appliance approval process
In Western Australia the technical regulator for the gas industry is Energy Safety, part of the Department of Commerce. The Australian Standards for appliance approval often refer to the important role of the technical regulator to set the local requirements. Energy Safety has produced a guideline to Type B appliance approval which clearly sets out the various steps that need to be followed.
Type B gas appliances can be of a type produced in significant numbers such as HVAC water heaters but are generally specifically designed as part of a specialist process and can be found in a diverse range of industries. Powder coating, spray painting, coffee roasting for example through to gas engines and turbines for power generation.
If you are considering purchasing or manufacturing an appliance that will be classified as Type B there are specific Australian Standards that have to be complied with, it’s these compliance requirements that C.G.E Services specialise in. Appliances are often built to a design acceptable in other parts of the world but can meet with difficulties for approval here in Western Australia.
If considering a Type B appliance some basic questions should be asked prior to purchase or manufacture. It’s important to realise that many man hours can be used re-configuring an appliance not to mention the additional cost of new components. In most cases it’s prudent to contact C.G.E Services in the early stages of the project. C.G.E Services can provide valuable compliance information at this early stage which can save a lot of time and design changes later in the project.
