MOVING GRATE SYSTEMS

MOVING GRATE SYSTEMS

IPM Isi Proje Makina offers modern combustion technologies through the Moving Grate Systems it has developed since 2002, delivering high efficiency, safe operation and low fuel costs in solid fuel boilers.

Our systems are designed specifically to burn low-calorific domestic coal, lignite, pellets, sawdust, olive pomace, hazelnut shells and many other biomass fuels at high efficiency. Moving grate technology ensures the fuel advances under control while the combustion process is continuously optimised for maximum energy efficiency. 

They can be used in newly built plants and can also be integrated easily into existing steam boilers, hot water boilers, high temperature hot water boilers and thermal oil boilers. 

Technical Specifications

• High-efficiency combustion system for low-calorific solid fuels
• Optimised combustion design in which moving and fixed grates work together
• Cr-Ni alloy cast grates withstanding operating temperatures of up to 900°C
• Hydraulic or mechanical drive system options
• Adjustable grate speed via an inverter-controlled gearbox
• Combustion control that can be optimised according to fuel type
• PLC-based fully automatic control system
• Automatic fuel feeding system
• Automatic ash discharge system
• Low noise operation
• Easy integration into existing boiler systems
• Mechanical equipment resistant to high temperature and abrasion

Fuel Compatibility

IPM Moving Grate Systems can be designed to operate at high efficiency with the following fuels.

• Domestic Lignite
• Low-Calorific Coal
• Pellets
• Sawdust
• Olive Pomace
• Hazelnut Shells
• Sunflower Husks
• Biomass Fuels
• Agricultural Waste
• Other project-specific solid fuel types

PLC-Controlled Automation

In moving grate systems all equipment is managed by a PLC-based automation system.

The automation system controls;

• The fuel feed rate
• The grate travel speed
• The combustion air
• The fans
• The ash removal system
• The safety equipment

simultaneously, keeping the system running at optimum efficiency at all times.

It reduces operator intervention to a minimum while creating safe and stable operating conditions. 

Combustion Technology

Thanks to the moving grate system, the fuel advances through the combustion zone under control.

With this design;

• Almost all of the fuel is burned.
• Unburned coal is prevented from passing into the ash zone.
• Uniform combustion is achieved.
• Carbon monoxide (CO) formation is minimised.
• Flue gas emissions are reduced.
• Fuel consumption is lowered.
• Boiler efficiency is increased.

Controlled primary air supplied from beneath the grate is distributed evenly across the entire combustion surface, delivering high combustion performance. 

Safety Systems

IPM Isi Proje Makina moving grate systems are equipped with a multi-layered safety infrastructure.

The system provides safe and uninterrupted operation through;

• Internal pressure control
• PT100 temperature sensors
• PLC safety algorithms
• Safety interlocks
• Fan and motor protection systems
• Emergency stop functions

The pre-furnace structure is manufactured as a special steel construction resistant to high pressure. 

Automatic Ash Removal System

The ash produced in moving grate systems is discharged continuously by the automatic ash removal system.

To reduce dust formation, different solutions such as;

• Water spray system
• Water bath system

can be applied.

This both simplifies plant cleaning and reduces environmental emissions. 

Advantages

• Efficient combustion of low-calorific coals
• Design suited to biomass fuels
• Maximum combustion efficiency
• Low fuel consumption
• Automatic fuel feeding
• Automatic ash removal
• PLC-controlled full automation
• Low maintenance requirement
• Quiet operation
• Easy adaptation to existing boilers
• Low emission values
• Long-lasting Cr-Ni alloy cast grates
