Type B Appliance - Stationary Gas Engines & Turbines
Electrical Control Systems Design
The requirements for a Type B appliance are given in AS 3814 – Industrial and Commercial Gas-Fired Appliances. The current issue of the standard is 2015.
This standard is deemed as a ‘prescribed standard’ to which compliance is mandatory. The application of the standard is supervised by the Technical Regulator in each Australian State.
From the abstract:
“The standard provides the minimum requirements for the design, construction and safe operation of Type B appliances that use any gas as a gaseous fuel to produce flame, heat, light, power or special atmosphere in any combination of these gases either together or with other fuels.”
A Type B appliance requires third party certification and approval before being put into service.

The special application requirements for stationary gas engines and turbines are given in Section 5.8.
The requirements include:
The requirements include:
- Safety shutoff for the valve system
- Gas turbine and gas engine purging
- Gas supply flexible connection
- Exhaust system to be fitted
- Ventilation of gas engine and gas turbine installations
- Requirements for ignition
- Emergency stop
- Over-speed
- Gas engine and gas turbine air / fuel ratio control
BESST provide electrical and control system design services for stationary gas engines. The engines are typically gas-ignition, gas-fuel, and reciprocating engines. Alternatively the engines are dual-fuel, reciprocating engines, using diesel and gas fuel.
To get Type B approval, the design requires the integration of the gas engine interfaces, controllers, engine wiring and auxiliary systems (ventilation) in such a way that compliance with the standard is achieved. BESST is able to provide designs to suit your application so that the gas system is typically classified as non-hazardous. BESST is also able to provide hazardous area classification should the system require such classification.
