Corner-Fired Warmup Gun System
4Pages

Smokeless Igniter Technology . This technology utilizes uniquely designed internal-mix atom-izers and low pressure drop flame stabilizers. The flame stabilizer is designed to fit the existing warmup gun buckets without modification. If no corner-fired oil guns exist, auxiliary air buckets can be modified to accept the oil gun flame stabilizer and CF igniter. The combination of properly designed atomizers and flame stabilizers assures reliable light-off, stable and attached flames, and no smoke (opacity <5%). > COENRs Corner-Fired (CF) Oil Warmup Gun is a low-cost performance upgrade for installation in the corner windbox of tangential-fired boilers for boiler warmup, main burner light-off, and main burner stabilization. The CF igniter was developed as a direct replacement for all types of existing warmup oil guns. Designed for a minimum of NFPA Class 1 service, the CF warmup gun allows for continuous operation with a heat input rating up to 80 MMBtu/hr.The COEN CF Warmup Gun is a proven solution for overcoming many com-mon ignitor operating problems. The warmup gun provides reliable light-off, smokeless operation (low opacity), short flames with no impingement on furnace tube walls, complete fuel burnout, no overheating of downstream fuel buckets, and minimal maintenance. The igniter can be equipped with a high energy spark as an option. This Direct IgnitionӔ assembly can be used to replace existing warmup guns and eliminates the need for sidewall horn igniter systems. The COEN CF Warmup Gun is also available with an op- tional retract system.

PATENTED SMOKELESS IGNITER TECHNOLOGY Each igniter system is custom-designed and fitted to a specific boiler and burner arrangement to ensure optimal conditions for combustion of the fuel. Basic CF Warmup Gun COENs patented Smokeless Igniter Technology of-fers a fundamental improvement in oil combustion com- pared to what was available to the utility industry in the past. The COEN technology focuses on the requirement for an igniter or oil burner to perform under non-ideal boiler conditions that exist on a cold start. These condi- tions include non-preheated combustion air, high excess air...

Smokeless Atomizer , the CF Warmup Gun can simplify operations from first fire and boiler warmup to bringing the unit online without coal. Direct Ignition CF Warmup Gun, Retractable orNon-Retractable Equipped with a high energy spark system (HEEI), the CF Warmup Gun becomes an efficient combination of igniter and warmup gun. This arrangement eliminates the need for sidewall horn igniters to ignite the oil. With direct ignition warmup gun systems installed between all coal mills, all sidewall horn igniters can be eliminated. With the broad turndown range of the CF WARMUP GUN...
