HTT Conversion catalytic Oxidizers
Well we've 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 our
customers utilize rental units of both electric and gas fired systems,
so wouldn't it be great if you could simply stock the core unit and
then mount
either a gas burner or an electric heating unit in 30 Minutes?
Well, now you
can!
TYPICAL
HTT
GAS/ELECTRIC
CATOX SYSTEM
HTT supplies one Fume Incineration
System containing a gas burner or electric heaters to raise
the temperature of the exhaust gases to the required operating
temperature. This assures maximum destruction of the VOCs in the
exhaust gas. The complete system is packaged 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
is 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 is installed
with SS anchors to maintain integrity while the lower chamber is
constructed of carbon steel and coated with an acid-resistant
epoxy coating.
CATALYST BED
Catalyst is supplied in
modular sections in separate frames. The frames come complete with
all mounting flanges and gaskets. The frames bolt directly to a
stainless steel
support grid inside the chamber of the retention zone. This allows the
EZ-Bolt
Catalyst modules to be easily accessed for removal and or
maintenance.
PREHEAT EXCHANGER
The system includes an integral
preheat exchanger for raising the temperature of the exhaust gases
prior to entering the firing chamber. The exchanger is a shell
and tube-type unit manufactured using easy clean 1 inch alloy tubes.
ELECTRIC HEATING SYSTEM (E OPTION)The system includes a process air electric heater for raising the temperature of the gases to operating temperature as required. System comes complete with an Incalloy sheathed tubular heater rated at 10-20 watts/sq. in. and 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 includes flame
safety, controls and safeties. A motorized modulating gas valve
regulates the burner output using digital controllers. Burner train
components are supplied separately for field installation.
Customer is to supply gas regulators as needed.
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 and it's complete. Removal and reinstallation takes less than
one hour, however, it's 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 includes one (1)
dilution air blower for maintaining minimal air ratio and for
controlling chamber temperature. The blower includes a control
damper and modulating actuator.
FLAME
ARRESTER (FA Option)
The system includes 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 such as model H12-002 for a
single channel type K TC. Other recorders are available that can
accept T/C, MA, or DC inputs for required sensors.
DILUTION
AIR CONTROL TEE (T Option)
The system includes 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 includes a spring return actuator that diverts up
the stack during a power failure.
CONTROL
OPERATION
The operator starts and stops the
system from the main panel or from remote inputs. Startup proves
the blower, start burner, prove set temperature and signal to
start
fume injection. Blower pressure and customer safety limits must
be
proven prior to burner ignition. Component failures shut down
the system and alert the operator. Indicator lights will display
fault.
The system is designed to operate
with a variable waste gas input while natural gas is controlled to
maintain a preset temperature. The system is 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 includes one (1)
Hoffman Nema 4 control panel for remote control and monitoring. The
system maintains a preset temperature utilizing a type K T/C and
4-20 ma digital controllers. System is monitored by Honeywell
DC-3000 temperature controllers for system operation, located
in the main panel. All controls and safeties are operated from
this
main panel. The controller modulates the heat input to maintain
temperature. Contacts are provided for remote start and stop,
pressure limit switch and for motor starter coil. PLC operation
is
optional.

Ft.DELIVERY: Typically takes 6 to 8 weeks following receipt of a valid purchase order, progress payments and all required approvals. INSTALLATION:
Installation requires running utilities to unit from source. We
suggest the gas train, supply duct and main panel are located
indoors. We separately provide any necessary components prior to
shipment of the main
unit. These components are to be installed prior to delivery of
main units.
