1 Introduction Product Description Audience The Winnox is a nozzle-mix type, low-emissions burner designed for direct and indirect air heating, and oven applications up to 1800°F (980°C). This manual has been written for people who are already familiar with all aspects of a nozzle-mix burner and its addon components, also referred to as “the burner system”. The burner package includes a combustion air blower and ratio regulator to fire over a wide gas turndown range at a controlled ratio.
2 Safety Introduction Capabilities This section is provided as a guide for the safe operation of a Winnox burner system. All involved personnel should read this section carefully before operating this system. Adjustment, maintenance and troubleshooting of the mechanical and the electrical parts of this system should be done by qualified personnel who has experience with combustion equipment.
3 Installation Introduction Gas Piping In this chapter you will find information and instructions needed to install the burner and system components. All the gas piping must comply with all applicable local codes and/or standards such as: Handling & Storage • NFPA Standard 54 Handling • ANSI Z223 • Make sure that the area is clean. Where to Get the Standards: • Protect the components from excessive temperatures and humidity.
Checklist Before Installation Intake To admit fresh combustion air from outdoors, provide an opening in the room of at least one square inch per 4,000 BTU/hr (1.17 kW). If there are corrosive fumes or materials in the air, then supply the burner with clean air from an uncontaminated area, or provide a sufficient air filtering system. For detailed information on how to install and connect a flamerod, refer to Info Guide 832.
Tube Shrouding Considerations 1 Slots 3 Combustor In applications where process air may flow perpendicular over the combustor, a metal shroud should be installed around the combustor that is 20% larger than the combustor diameter with a length that covers the combustor slots by 100 mm (4"). Slot dimensions can be found in Winnox datasheet, series 111. Chamber Wall Fiber Insulation Make sure the chamber wall Y is strong enough to support the weight of the burner Z.
Gas Piping CAUTION Burner Piping The burner is factory assembled and shipped as ordered. NOTE: If it is necessary to redirect piping, remove the outer four bolts only X. Rotate the rear cover and replace bolts. When reassembling, be sure that: Ŷ Do not alter the bypass regulator. The NFPA requires that the bypass regulator ] be appropriately vented and protected. • For applications in which the Winnox is operating indoors, a vent limiting device is installed in the bypass regulator.
Checklist After Installation To verify the system was properly installed, perform the following checks: 1. Be sure there are no leaks in the gas lines. 2. Be sure all the components contained in the flame monitoring and control systems are properly installed. This includes verifying that: • all the switches are installed in the correct locations. Bracket • all wiring, pressure, and impulse lines are properly connected. 3.
Adjustment, Start & Stop In this chapter, you will find instructions on how to adjust, start, and stop the burner system. Become familiar with burner control methods before attempting to make adjustments. DANGER Ŷ The Winnox burners are designed to mix fuel with air and burn the resulting mixture. All fuel burning devices are capable of producing fires and explosions if improperly applied, installed, adjusted, controlled, or maintained. Ŷ Do not bypass any safety feature; fire or explosion could result.
butterfly valve is closed when the shaft slot is perpendicular to the direction of air flow through the butterfly valve. Back b. Rotate the air butterfly valve shaft to a fully closed position. (Holes in the butterfly valve will supply low fire air.) When firing into a positive chamber pressure, rotate the air butterfly valve from the closed position in the direction of actuator travel to obtain a minimum 0.3" w.c. (0,8 mbar) air differential pressure. Closed Open Open in this direction only Figure 4.
Step 3: Ignite the Burner on the datasheet for your burner. Low Fire Start 10.After ignition, verify low fire flame: WARNING Ŷ These procedures are written with the assumption the burner has a flame monitoring control system installed and operating. A proper purge cycle must be part of the system and purge timing should not be bypassed. Tap E Main gas shut-off valve train a. Shut off gas. When chamber temperature is below 250°F (121°C) shut off combustion air blower. b.
6. Set system control to stay at low fire during and after ignition sequence. 7. Attempt to ignite burner. 8. During trial for ignition, adjust bypass pressure regulator Y and adjustable limiting orifice Z to achieve the appropriate 'p between Tap E and the chamber as listed in the appropriate datasheet. CW for more gas NOTE: If viewing the flame, it should be blue with flashes of yellow. The flame should be completely within the combustion tube.
7. Turn bias adjusting screw X slightly to achieve 0.1" w.c. (0.3 mbar) 'p between Tap B and the combustion chamber. Repeat ignition sequence until burner lights. NOTE: If viewing the flame, it should be blue with flashes of yellow. The flame should be completely within the combustion tube. When firing propane or butane, a proper low fire flame may have sustained flashes of yellow. 7. Measure gas pressure at the burner inlet Y and verify the pressure is within the range specified on the datasheet. 8.
Maintenance & Troubleshooting This section is divided into two parts. The first part describes the maintenance procedures, and the second part helps you to identify problems that may occur and gives recommendations on how to solve these problems. Preventative maintenance is the key to a reliable, safe and efficient system. The following are suggested guidelines for periodic maintenance. Burners in severe environments or operational conditions should be checked more frequently.
CAUTION Ŷ Do not attempt to remove the rear cover by removing the inner circle bolts \. Internal burner parts will be damaged. e. Remove bolts ]. f. Remove the rear cover / nozzle assembly Z from the burner housing [. g. To reassemble, follow this sequence in the reverse order. NOTE: The combustor can be inspected only by removing the burner from the chamber wall or entering the chamber. Figure 5.
Troubleshooting Problem Possible Cause The low fire flame is weak or Not enough gas flowing to the burner. unstable. Not enough air. Solution Adjust the ratio regulator or bypass fuel adjustable orifice valve to increase the gas flow. Check for proper blow rotation. Check air filter for blockage. Compensate for chamber by opening the low fire air butterfly valve position. The burner goes out when it Not enough gas pressure into the ratio cycles to high fire. regulator. Check the start-up settings.
