Continental Controls Corporation - Fuel Controls for Gas Turbines and Reciprocating Gas Engines

Continental Controls Corporation is a leading supplier of fuel control products for both natural gas engines and gas turbine engines. All of CCC’s valves include a CPU integrated into a "smart valve concept". Mechanically all of the fuel valves provide an exceptionally fast response with minimal friction and hysteresis, and an integrated fuel measurement.

Electronic gas fuel valve

The GV1 gas valve operates as a variable pressure controller monitoring and controlling the gas injection pressure to either the carburetor or mixing venturi of the engine. The valve will respond within 30ms to a change in downstream pressure, which enables the valve to react to load changes much more quickly than a traditional AFR valve that only reacts to changes in the oxygen feedback from the engines exhaust.

The GV1 operates with either naturally aspirated gas engines or (by adding a turbo balance line) with turbocharged engines. The valve can control many types of gaseous fuels such as natural gas, field gas, propane, or various bio-fuels or land fill gasses.

Air fuel ratio control and improved fuel mixing for natural gas engines

By replacing a traditional mechanical Carburetor with a state of the art electronic carburetor the engine can run in either rich or lean burn mode. This can allow for maximum fuel economy while producing the minimum level of unwanted emissions. The Electronic Carburetors are available for engines from 25 hp to approximately 500 hp. In addition to improved engine performance the electronic carburetor will provide reduced maintenance over the traditional carburetor.

By combining a precisely designed mixing venturi and a very fast acting, variable pressure regulator, and integrated control for a wide range oxygen sensor, the EGC 2 and EGC 4 provide the fastest acting and most effective air fuel control and fuel mixing currently available for natural gas, propane, or other alternative gaseous fuel.

Fuel control valves for gas turbines

CCC makes a range of fuel control valves for most gas turbines up to about 60,000bhp. These valves all include on board CPUs, with embedded software making them the most sophisticated fuel valves available for turbine engines.

AGV 10/50 gas turbine fuel valve

The AGV 10/50 is a two-stage gas actuated valve that offers exceptional control and diagnostic information for small to mid sized gas turbines. The valve compares the fuel demand signal with a mass flow calculation in the valve to assure the most accurate fuel metering available. The flow measurement signals as well as other diagnostic measurements are available via RS 485 Modbus protocol. Because of the precise fuel flow measurement in the valve, the turbine starts more reliably and runs at a more stable speed than with other fuel valves. The AGV 10/50 is almost impervious to dirt or liquids and can withstand the most demanding environment. These electronic fuel valves require only 24vdc and about 1 amp which allows for much simpler installation and retrofit than some competing actuators.

ALV 10 liquid fuel valve

The ALV 10 offers precise fuel metering and measurement of liquid fuels such as diesel #2 or kerosene, as well as gas turbines. It includes a turbine meter to measure fuel flow and it also operates on only 24vdc.
