HTT
Conversion catalytic Oxidizers
Well we have finally done it.
We have the first conversion
recuperative catalytic oxidizer that can
operate with either gas or electric as the
heating source. Some of out customers have
rental units of both electric and gas fired
systems. Wouldn't it be great if you could
stock the core unit and then mount either a
gas burner or an electric heating unit in 30
Minutes? Now you can.
TYPICAL
HTT GAS/ELECTRIC CATOX SYSTEM
HTT shall supply one Fume
Incineration System. The system shall use a
gas burner or electric heaters to raise the
temperature of the exhaust gases to the
required operating temperature. This will
assure maximum destruction of the VOC in the
exhaust gas. The system shall be packaged
complete with an integral preheat exchanger,
Inconel sheath low watt density heating
elements or gas burner, precious metal ceramic
type catalyst module, refractory lined
processing chamber, and the field installed
stack.
CATOX SYSTEM
CHAMBER
The Catox System
shall be constructed of 304 stainless steel
(Note: We use 316 L for HCl solvent
applications) and insulated with a combination
of Ceramic Fiber and high temperature
insulating materials. The refractory shall be
installed with SS anchors to maintain
integrity. The lower chamber shall be
constructed of carbon steel and coated with an
acid resistant epoxy coating.
CATALYST BED
Catalyst shall be
supplied in modular sections in separate
frames. The frames will be complete with
mounting flanges and gaskets. The frames
will bolt directly to a SS support grid
inside the chamber of the retention
zone. The EZ-Bolt Catalyst modules may
be easily accessed for ease of removal
and maintenance.
PREHEAT EXCHANGER
The system shall
include an integral preheat exchanger for
raising the temperature of the exhaust gases
prior to entering the firing chamber. The
exchanger shall be a shell and tube type unit
manufactured using easy clean 1 in alloy tubes.
ELECTRIC HEATING SYSTEM (E OPTION)The system shall include a process air electric heater for raising the temperature of the gases to operating temp as required. System shall be complete with an Incalloy sheathed tubular heater rated at 10-20 watts/sq. in, mounted on a stainless flange with a weather-proof terminal housing, and screw type terminals.
The system is available with a
packaged gas fired burner, for raising the
temperature of the gases to operating
temperature as required. System shall be
complete with flame safety, controls and
safeties. A motorized modulating gas valve
will regulate the burner output using digital
controllers. Burner train components are
supplied loose for field installation.
Customer shall supply gas regulator.
HEATING SYSTEM CONVERION
The
top of the system contains a flanged connection
for mounting the electric or gas heating system.
Select the heat source and bolt either the
burner or the electric elements to this flange.
Each heat source comes with its own panel which
is mounted to the system base. Connect the
thermocouples to the panel, you are finished.
Removal and reinstallation takes less than 1
hour. It is sometimes faster to replace a
troublesome component or panel with a
new one than to spend time
field troubleshooting.
ID
BLOWER (IDB Option)
The system shall include one (1)
dilution air blower for maintaining minimal air
ratio and for controlling chamber temperature.
The blower shall include a control damper and
modulating actuator.
FLAME
ARRESTER
(FA Option)
The system shall include one (1)
flame arrester to prevent the gases and flame
from backing up the supply duct.
DATA
LOGGING
(DL Option)
Package may include an optional
Data Logging system as manufactured by HOBO and
may be model H12-002 for a single channel type K
TC. Other recorders shall are available that
will accept T/C, MA, or DC inputs for required
sensors.
DILUTION
AIR
CONTROL TEE (T Option)
The system shall include one (1)
waste gas diverting tee for closing off the
stack during operation or for closing off the
waste gas to the oxidizer when the system is not
operational. Package shall include a spring
return actuator that will divert up the stack
during a power failure.
CONTROL
OPERATION
The operator shall start and
stop the system from the main panel or from
remote inputs. Startup shall prove the blower,
start burner, prove set temperature, and signal
to start fume injection. Blower pressure and the
customer safety limits must be proven prior to
burner ignition. Component failures will shut
down system and alert the operator. Indicator
lights will display fault.
The system shall be designed to
operate with a variable waste gas input. Natural
gas will be controlled to maintain a preset
temperature. The system will be able to self
regulate the fuel input to both maintain
temperature and adjust conditions to match the
flow of the waste gas stream.
CONTROLS
The package shall include one
(1) Hoffman Nema 4 control panel, for remote
control and monitoring. The system shall
maintain a preset temperature utilizing a type K
T/C and 4-20 ma digital controllers. The system
shall be monitored with Honeywell DC-3000
temperature controllers for system operation
located in the main panel. All controls and
safeties are operated from this panel. The
controller will modulate the heat input to
maintain temperature. Contacts will be provided
for remote start and stop, pressure limit
switch, and for motor starter coil. PLC
operation is optional.

Installation will require running utilities to
unit from source. We suggest the gas train,
supply duct, and main panel are located
indoors, we will provide these components
loose prior to shipment of the main unit to be
installed prior to delivery of main units.
