CLEAN STREAM AFTERBURNERS REDUCE SMOKE & ODOR
Are you receiving complaints about your exhaust plume?
Are you interested in being more environmentally friendly?
Do you need to comply with emission control requirements?
We can help.
Our "Clean Stream Afterburners" are used for emission control in several industries, including commercial Coffee Roasting. They
work by heating exhaust gasses up to high temperatures, which effectively breaks down the fine particulate, smoke, odor, VOC and CO produced during the coffee roasting process. The result is a clean exhaust stream, virtually free of smoke and odor
. ​
We design and build afterburners to meet all your emission control needs. Please contact us for more details and finance options.
The Clean Stream Afterburner model CSA-400-CAT is a "catalytic oxidizer" system designed to work with most 5-30 Kilo industrial coffee roasters.  It can handle an exhaust flow of up to 400 CFM (cubic feet per minute) from either the roaster only or the combined roaster and cooling rack.
This afterburner is placed after the chaff collector and is designed to reduce smoke, odor, fine particulate, CO and VOC from the exhaust stream with  a destruction efficiency of about 95%. The afterburner is typically used for the roaster exhaust only, but smaller roasters with combined roaster and cooling rack blower are usually compatible. If you're unsure what size afterburner you need, p
lease contact us for details.
Can handle up to 400 CFM max exhaust flow (other sizes available!)

TYPICAL CATALYTIC OXIDIZER SYSTEM
The Catalytic Oxidizer is mounted downstream of the chaff collecting cyclone. The system shall raise the temperature of the exhaust gases from the coffee roaster to the required operating temperature, typically 750 F.  This will assure maximum destruction of the vapors and particulate in the exhaust stream.  The system shall be packaged complete with natural gas burner, refractory lined chamber, control panel, support base, and the required components as described below:
TYPICAL COMBUSTION CHAMBER
The system will look very similar to the photos above. A 316L Stainless Steel liner lines the interior of the system. A 3-4.5” layer of Ceramic Fiber refractory insulation keeps the outer shell cool enough to touch.  The burner assembly will be concealed on the lower part of the system and will fire horizontally into the chamber. The waste gas inlet connection is on the side and will flow horizontally into the chamber. The inlet is tangentially mounted which creates a swirling inside the chamber which in turn increases destruction efficiency.  The exhaust stack connection duct will be on the top and flow vertically up and can either be a straight duct 3” long or flanged depending on customer preference.
PACKAGE BURNER
The system shall include (1) Midco EC-300 Propane/Natural-gas fired burner with integral combustion blower for raising the temperature of the gases to operating temperature as required.  System shall be complete with flame safety controls and safeties. One (1) modulating motor with a gas valve will regulate the fuel using a digital controller.  The burner has a max output of 300k btu/hr, but will typically use appx 150-250k btu/hr. This is not a “low-NOX” burner.
INTEGRATED CATALYST MODULE
The catalyst allows the afterburner to be highly effective at a much lower operating temperature than a normal thermal oxidizer. At 750 F, >95% of smoke, odor, VOC and CO will be removed. The system will include a ceramic catalyst module featuring a platinum and palladium substrate. The catalyst module will be accessible and removable for routine cleaning and occasional replacement. Life expectancy of the catalyst is typically 30-40k hours of use or 10 years. The lower operating temperatures equate to a substantial fuel savings over a traditional thermal oxidizer system.
CONTROLS
The package will come standard with a control panel for remote control and monitoring. All controls and safeties are operated from this panel. Combustion chamber temperature is read by a type-k thermocouple. A Honeywell UDC-1200 digital temperature controller is used to maintain a pre-set temperature by use of a motorized Belimo actuator with a gas valve. Contacts will be provided for remote start and stop and pressure limit switch.
CONTROL OPERATION
The operator shall start and stop the system from the main panel or from remote inputs. Blower pressure and the customer safety limits must be proven prior to burner ignition.  Component failures will shut down the system and alert the operator.  Indicator lights will display when the burner is firing and if there is an ignition fault. The system shall be designed to operate with a variable waste gas input. Natural gas/propane 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. The afterburner can be set to simply run all day or can be cycled on and off with each roast in order to save fuel.
CONFIGURATION OPTIONS
The customer can choose which side we mount the inlet duct, power cord, and gas connection (left or right when looking directly at the system). The top photos show the connections on the left, and the bottom photo shows the connections on the right. The main system base, control panel and pedestal are typically powder coated black, but a different color can be chosen by the customer. The control panel can be upgraded to the brushed stainless version (shown in photos) at an additional cost. When placing your order, please specify your preferences.

TERMS:
In order to keep production moving at an ideal pace, full payment via wire transfer is preferred.
DELIVERY:
System shall be ready for pickup 4-6 weeks after the receipt of a valid purchase order, payment, and all required approvals. We can assist with freight. Rush fabrication/delivery is available. We will bolt the system to a skid and wrap in layers of cardboard and plastic wrap for safety in transit. Typical freight dimensions are 48” x 48” x 82” and appx 950 lbs.
STORAGE:
If needed, we can store the system onsite for up to 1 month after receipt of full payment.
INSTALLATION:
We shall provide phone assistance and guidance for installation and mounting the unit. Installation should be done in accordance with local codes. Customer will provide on-site labor/contractors for necessary assembly, electrical and gas connections.  Installation should adhere to local code requirements. Some main installation points to cover:
Gas-
Install an adjustable gas flow regulator which can provide 6-14” Water Column to the afterburner. Run gas from source to the afterburner.
Electric-
Connect the supplied 3-prong power cord to a standard outlet with 15 amp breaker. A dedicated breaker is suggested if possible.
Connection Duct-
Install quick-clamp style connection duct from chaff collector outlet to afterburner inlet. Adapters may be needed depending on duct sizing. We recommend Nordfab and US-Duct.
Exhaust Stack-
Install insulated exhaust stack. We always recommend using a stainless double-walled insulated exhaust stack capable of handling 1000 F continuous. Local code may require a positive pressure system. Metal-Fab “PIC” insulated double wall positive pressure exhaust stack is a good option to consider. An approved roof penetration should be used and a rain cap with plenty of airflow is needed in order to keep any back-pressure at a minimum. A high flow stack termination with minimal restriction would be best. If bends are needed, we suggest using no more than a 45 degree in order to limit back-pressure. Stack should vent above the roofline in accordance with code.
