Wood gasifier with CHP 250 kW
Demand for industrial applications has led to the development of systems with a higher output range. DC gasifiers and CHP units with 250 kW are nowavailable in the wp3 series, with a number of technical innovations.
The systems are manufactured from high-quality, industry-standard components for a long service life. The core of the system is a direct-current fixed-bed (DC) gasifier developed over many years in combination with a specially adapted gas filter system. System solutions have also been developed for other plant components such as the fuel lock, gas cooling and coal dust discharge, which are less susceptible to faults and very easy to maintain.
For the CHP unit, we use MAN biogas engines with electronic ignition and high-quality synchronous generators. The 4-valve technology of the wp3.250 further increases efficiency.
New features of the wp3.series
Module GV
- Gasifier with impurity discharging system, smaller stones and pieces of metal are ejected during the process, the system achieves more full load hours due to less cleaning effort.
- Lifting devices for filter and gasifier maintenance are directly attached, so there is no need for equipment on the ceiling and pipes can be routed directly above the system.
- CHP unit with 4-valve-technology motor brings higher electrical efficiency.
- Larger exhaust gas heat exchanger provides higher thermal efficiency.
Wood chip CHP 250 kW
The development of the 250 kW wood chip CHP unit is based on the requirement to ensure a stable gas generation process with standard wood chips, including fine and bark fractions, for a consistently high electrical and thermal output. With our innovative technology, we have developed a future-oriented system for decentralized energy supply. A step towards independence from third-party providers while making optimum use of local resources.
