Combustion Grates and Rotary Kilns
The product package offered by Revi Tec Feuerungsbau AG, a subsidiary of TM.E. S.p.A., includes complete combustion grates with air-cooled, water-cooled, or combined cooling technology. The service package includes design, construction, commissioning, support, and maintenance.
In addition to grates, TME is a supplier of rotary kilns for complex applications related to the treatment and waste-to-energy conversion of special waste, developing highly specialized projects for plants capable of treating non-homogeneous waste with high calorific value.
Reliability and ease of maintenance at the heart of the project
The annual operating hours of the grates are high as a result of free access to critical components during operation, rapid start-up and shutdown, and synchronous control of grate speed.
Optimized Combustion with the ACC System
The grate technology ensures uniform boiler loading (thermal, corrosion, abrasion, and fouling) through efficient combustion provided by the Automatic Controlled Combustion (ACC) system and energy load distribution (air passage slots, no gaps between the grate bars, and possibility of lateral expansion).
Many years of experience confirm low refractory wear, uniform thermal load, and reduced slag by controlled air distribution and stable combustion chamber load.
The main grate furnace features:
- Air or water cooled grate surface for low/high calorific values
- Drive elements and other flexible connections outside the grate and easily accessible during normal operation
- No installations under the grate (no bearings/drives, no hoses for cooling water/hydraulic oil, no valves, cylinders/position encoders, etc.)
- Water cooled grate side expansion system with adjustable spring loaded devices
- Self cleaning air slots on the grate surface ensuring a controlled combustion
- Any grate slope between 0° and 12°
- Hydraulic drive for the grate modules (3 pieces) and for the feeder with two hydraulic cylinders for each part. This includes proportional valves and integrated synchronous speed control/position encoding
- Five or six air zones with regulating dampers and with speed-controlled fans for each zone
- Heat recovery for water cooled grate surface parts by primary/secondary air preheating
- Superheated steam – air preheater for further preheating integrated in the Automatic Controlled Combustion (ACC) for low or highly variable calorific values
- Freely adjustable ACC, self contained or integrated in DCS.
