Typical HTT Thermal and Catalytic Oxidizer Systems

The HTT Fume Incineration System is designed to raise the temperature of the exhaust gases to the required operating temperature to assure maximum destruction of virtually all VOCs in the exhaust gas. The system is available as a complete package that includes natural gas burner, refractory lined chamber, stack, controls and any of the required optional components described below.

REFRACTORY CHAMBER
The refractory chamber is constructed of carbon steel and lined with a combination of ceramic fiber and high temperature insulating materials The completed chamber is installed on a steel skid with stainless steel anchors and suitable cross-bracing to maintain integrity.Click to enlarge To ensure the longest possible service life, the refractory chamber is solvent washed and then finished both inside and out with an acid resistant, high-temperature epoxy coating. Additional paint is supplied for Customer touch-up, should the need arise.

The chamber comes equipped with sight ports, thermal wells and a service access door.

CATALYST BED (CAT Option)
The catalyst is supplied in the form of modular components mounted within separate EZ-Bolt frames. The EZ-Bolt frames come complete with mounting flanges that bolt directly to a stainless steel support grid either inside or outside the chamber. On SVE systems, the EZ-Bolt Catalyst modules may be installed externally for ease of removal and maintenance.

SVE applications with high VOC levels during the first few months of operation should use an FM-G, but when VOC levels drop, a separate catalyst module may be added to dramatically reduce fuel usage. Click to enlargeThe CAT module can be purchased as part of the original order, or added later as required. On SVE applications, the module is mounted to a flange located under the stack transition section.

PREHEAT EXCHANGER (HR Option)
The system also includes an integral preheat exchanger for raising the temperature of the exhaust prior to the gases entering the firing chamber. The exchanger is a plate-type unit as manufactured by Exothermics Eclipse and Des Champs Labs. Exchanger comes complete with computer runs.

NATURAL GAS BURNER (G Option)
The fume incineration system includes one (1) packaged gas-fired burner for raising the temperature of the gases to set operating temperature as required. The system is complete with flame safety, controls and safeties. A motorized modulating gas valve regulates the burner output using Honeywell digital controllers. Burner train components are supplied loose for field installation.

The natural gas regulator is not included with the system and must be supplied by the Customer prior to, or at the time of system installation.

STAINLESS CHAMBER (SS)
The chamber is constructed of 304 stainless steel and is insulated with a combination of ceramic fiber and high temperature insulating materials. It is mounted on a channel steel skid with suitable cross bracing and includes sight ports, thermal wells and access doors or panels. To maximize service life, the chamber is coated with an acid-resistant epoxy coating.

PACKED TOWER SCRUBBER (PTS)
The packed-tower scrubber is constructed of FRP and includes a quenching section, venturi, circulation pump, filler valve, level sensor, liquid storage, packed tower, and demister pad. All components are skid mounted for ease of assembly.

The scrubber is designed to remove any fumes present in the gases before discharge into the atmosphere. The gases contact the scrubber water to condense the fumes and wet the particles while also serving to clean the interior walls of the housing. A mixing section, or packed-tower accelerates the gas flow and maximizes the collection of any pollutants that may be present. The demister separation section removes ultra fine droplets and particles prior to being drawn up to the atmosphere.

PLC CONTROLS (PLC)
The operator has the ability to start and stop the system from the main panel or from remote inputs. Startup both energizes and proves the blower, scrubber, burner, set temperature and signal to start fume injection. Blower pressure and the Customer safety limits must be proven prior to burner ignition. Any component failures will shut the system down and alert the operator while panel indicator lights will display the fault(s).

The system is designed to operate utilizing variable waste gas input. Natural gas will be controlled to maintain a pre-set temperature while the system is able to self-regulate the fuel input to both maintain the desired temperature and adjust conditions to match the flow of the waste gas stream. Note: the Variable Frequency Drive (VFD) is supplied by other vendors.

ELECTRIC HEATING SYSTEM (E)
Included with the system is a Gaumer Model IDH electric process air heater for raising the temperature of the gases to operating temperature as required. Completing the system is an Incaloy sheathed, tubular heater rated at 20 watts/sq. inch. The heater is .475-inches in diameter and is mounted in a stainless frame with a moisture-resistant terminal housing and potted terminals.

INDUCED DRAFT BLOWER (B Option)
The ID Blower is a centrifuge-type, arrangement #9, complete with shaft seal, drilled inlet and outlet flange, lean-out door, V-belt drive with OSHA guard and a 1750 RPM TEFC Motor, 230/460/3/60. The blower is designed to handle a 10-inch WC pressure drop at design flow. Note: the starter and disconnect are supplied by other vendors.

FLAME ARRESTER (FA Option)
The system includes one (1) flame arrester to prevent the gases and flame from backing up the supply duct during momentary high VOC conditions.

AIR CONTROL TEE (T Option)
One (1) waste gas diverting tee is included for closing off the stack during system operation, or for closing off the waste gas to the oxidizer when the system is not operational. The system package also includes a spring return actuator that will divert gases up the stack during a power failure.

CONTROL OPERATION
The operator has the ability to start and stop the system from the main panel or from remote inputs. Startup both energizes and proves the blower, scrubber, burner, set temperature and signal to start fume injection. Blower pressure and the Customer safety limits must be proven prior to burner ignition. Any component failures will shut the system down and alert the operator while panel indicator lights will display the fault(s).

The system is designed to operate with a variable waste gas input. Natural gas will be controlled to maintain a pre-set 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 system package includes one (1) Hoffman Nema 4-control panel for remote control and monitoring. The system maintains a pre-set temperature utilizing type K T/C and 4-20 ma digital controllers and is continuously monitored for correct operation with Honeywell DC-3000 temperature controllers located in the main panel. All controls and safeties may be operated from this panel.

The controller is designed to modulate the gas flow to maintain a consistent operating temperature. Contacts are provided for remote start and stop along with a pressure limit switch along with contacts for the motor starter coil.

HTT associates provide off-site technical assistance for control changes at no additional charge during the life of the equipment. Note: Travel and living expenses are extra.

Optional - Package may include an optional multi-point strip chart recorder. Recorder accepts T/C, MA, or DC inputs for required sensors along with inputs from the optional monitors. The panel includes Nema 4 control switches, indicator lights and terminal strip connectors.
