9482023 Hot Water Boiler Plant Schmid 2400 kWth with moving step-grate
This Schmid boiler features a durable, electronically controlled,
water-cooled moving grate, designed to burn a wide range of fuels from
wood pellets to wood chips and waste wood. Installed in 2012, the
plant operated on wood pellets until December 2022.
It is a complete system in good condition, housed in a
concrete-element building, with two large pellet silos and a hot water
accumulator tank for heat load balancing. These auxiliary components
are optionally available to interested buyers.
The boiler is equipped with load-controlled primary and secondary
combustion air fans, as well as a speed-controlled exhaust gas fan,
ensuring high combustion efficiency and low electrical power
consumption. The two-stage combustion design minimizes NOx
emissions.
Its robust triple-layered ceramic and steel combustion chamber
incorporates flexible expansion joints, allowing thermal expansion and
contraction, thereby extending furnace life. The boiler also features
automatic compressed-air soot blowers and an automatic ash removal
system.
Combustion is managed by a control system with lambda sensors, which
continuously monitor performance to maintain optimal efficiency.
Operation is handled through the Schmid Control System with a local
touch-screen interface, which can be connected to a remote PC for
unattended operation.
