GAS PULSE TECHNOLOGY
The Thermal Image and Graph show the high degree of temperature control from the Gas Pulse principal. At Low Fire (0%) the average surface temperature of the heater is 300-350 F. (149-177 C.), while at High Fire (100%), the average temperature is 850-900 F. (454-482 C.) depending on heater orientation and position in an oven.
Zoning with Gas Pulse Technology
Flameless Catalytic heating which has brought energy cost savings to numerous thermo formers and paint finishers, now has a well proven method of control – Gas Pulse System (GPS).
The GPS unit is simple, cost effective and offers the option of multi zone configuration, permitting accurate and repeatable heating profiles for the catalytic heating system. Vulcan has pioneered Gas Pulse Technology, having installed many hundreds in both the finishing and thermo forming industries to control catalytic heaters. Typical gas industrial control valves, are totally unsuitable for controlling catalytic heaters. GPS has been proven to save gas consumption over other industry control valves.
Controlling the GPS
Control of the GPS is via one of two operator control types. For systems with less than five control zones, a simple percentage timer may be used. For systems with a greater number of zones, a PLC based control with an intuitive operator interface, offers the customer the best solution for multi zone systems, with recipe storage, system diagnostics functions and global increase / decrease of any heating profile.
Gas Pulse Hardware
Gas pulse technology uses electrically actuated solenoid valves, to cycle the gas supply between flow rates of 100% and 20%. Longevity and reliability have been the hallmarks for this technology, and synchronizes very well with the mechanics of the flameless oxidation process within Vulcan's patented catalytic heaters. By alternating between the high and low flow rates, the entire depth of catalyst is used, ensuring an even heat distribution across entire heater face at all percentage settings.
