How it Works

An Overview

Your new MX-900B Wood chip-fired Hydronic Boiler (hot water
heating boiler) is a very modern version of a very old and time-proven
method for properly burning solid fuels; called the "under-fire stoker
grate" method.
What sets your MX-900B system apart from previous older
generations of under-fire stoker grate systems is that the MX-900B
system makes use of modern advances in controls technology and
knowledge of combustion chemistry, along with advances in materials
science and modern manufacturing methods, to provide you with a
rugged, highly fuel efficient and low maintenance automatic wood
chip-fired combustion system.
This How it Works narrative is written to guide you through each
functional sub-assembly of the MX-900B Combustion System, so that
you will gain a clear understanding of the entire unit.
MX- 900B Control System:
The automatic control system of the MX-900B system is a modern
version of proven combustion control strategy. The MX-900B Control
System hardware consists of an industrial-duty programmable logic
controller (microprocessor-based PLC), touch-screen Operator
interface control / view panel, three variable speed AC motor
controllers, and a very carefully selected array of robust automation
sensors.
These industrial-duty controls components are orchestrated in unison
through a carefully designed, and extensively field tested, set of
software programs that are permanently stored in the memory of the
programmable logic controller. The control system is designed to
ensure safe operating conditions are maintained at all times, and to
initiate an automatic shut-down in the event of a fault.
