WORLD’S LEADING SPECIALIST FOR
GAS TREATMENT SYSTEMS AND FLARING TECHNOLOGY

Creating a safe work environment and reducing the carbon footprint are the key reasons for pre-draining gas from coal prior to mining. 
Once the methane gas is drained and captured, the gas can be utilised or destroyed in a high temperature flaring facility The gas could be used for power generation or heat recovery

In those cases the Hofsttter enclosed combustion system is applied as safeguarding and emergency system.
Hofstetter closely collaborates with Watergasrenew Pty from Australia.Watergasrenew PTY has extensive knowledge and experience in coal mine operations and gas extraction systems .This collaboration makes it possible to comply with the most stringent mining regulations and offer the full engineering package including FMEA,HAZOP ,cause & effect analyses .Through this in depth knowledge we are able to give the best possible technical and most economical advise how to handle your de-gassing issues.

• CFM4C - Coal mine gas flare
• CPM - Degassing system for coal mines
• Mobile Degassing Systems

The HOFGAS-CFM4c high temperature flare provides safe and environmentally friendly combustion of coal mine gas (Goaf-and Coleseam gas).
HOFGAS-CFM4c flare is able to burn methane concentration from 20 vol.% up to 95 vol.%. 

For each specific project the HOFGAS-CFM4c gas flare is designed to the specific customer requirements  and coal mine gas composition.

Features

• Efficient combustion of mine gas
• Automatic temperature control
• Controlled and concealed combustion
• Insulated combustion chamber
• High safety standard, fulfilling the latest ATEX standards

Customised solutions for safe degasification of coal mines with reliable processing of the methane gas for electricity or heat generation.

HOFGAS-CPM is comprised of one or several blower stations and the necessary components for faultless degassing. Defined control and regulation concepts guarantee safe and efficient operation.

• Customised solutions
• Safe and reliable degassing of closed and operating mines
• Processing of the gas for recycling
