Key Features

HRTOH-H spiral-wound waste heat boilers are designed for systems in which process waste gases, or biogas / syngas obtained from gasifiers and similar equipment, are used as the heat source to meet heat demands for various purposes.

The spiral-coil, horizontal or vertical design allows high-efficiency operation.

With heat transfer oils of suitable chemical composition, it can safely reach a high operating temperature such as 300oC  at an operating pressure of 6 bar.

Thermal oil boilers designed so that the oil velocity inside the coil is of the order of 2,5 – 3 m/sn preserve the chemical structure and the heat-carrying capacity of the heat transfer oil.

Thanks to its damper-motorized flap and the gas-side bypass built into its own body, there is no cost for a separate bypass duct.

Pressure losses on the oil side and the gas side are low. The investment cost and the energy consumption of the selected equipment are therefore lower.

Heat bridges that could be created by the lifting and insulation substructure elements on the boiler body are prevented, so heat losses are reduced to a minimum.

It can be manufactured with an open expansion tank or a closed expansion tank with a nitrogen blanket.

Service doors and easy disassembly make repair and replacement of the spiral tubes straightforward.

Optionally offered “Automatic Ash Extraction System” and  “Automatic Tube Cleaning System“ such as optional systems that allow unattended operation, ensure efficient, stable and fully automatic controlled running.

The flue gas filter selected according to the chemical properties of the waste gas  (“Multicyclone”, “Cyclone”, “Wet Flue Filter”,  “Bag Filter”) keeps emission values below the permitted limits.

High-quality safety equipment provides safe and stable operation.

The PLC-controlled touchscreen control panel makes operation straightforward, and remote access from mobile devices provides fast technical support anywhere in the world.

Delivered with long-life insulation that keeps heat losses to a minimum.

Manufacture in accordance with EN12952 and the PED2014/68 CE directive

Weld inspection on our boilers is carried out by non-destructive testing (NDT) within the scope and ratios set out in EN 12952-6.

Our welded fabrication is carried out by certified welders in accordance with approved WPS and WPQR. MIG-MAG and SMAW welding techniques are applied in manufacture in line with the standards.
