NATURAL GAS GENERATORS
TECHNICAL DATA INTRODUCTION
COGENERATION & TRIGENERATION GENERATORS
A gas engine is an internal combustion engine that runs on gaseous fuel, such as coal gas, producer gas, biogas, landfill gas, or natural gas. Gas engines refer to heavy-duty industrial engines capable of running continuously at full load for periods approaching a high fraction of 8,760 hours per year. Gas engines, any of a class of internal combustion engines that generate power by burning a volatile liquid fuel (gasoline or a gasoline mixture such as ethanol) with ignition initiated by an electric spark. They can be built to meet practically any conceivable power-plant application requirements, the most important being passenger automobiles, small trucks and buses, general aviation aircraft, outboard, and small inboard marine units, moderate-sized stationary pumping, lighting plants, machine tools, and power tools.

The marine generator is not much different than any generator. A marine generator is typically powered by diesel or gasoline to produce energy that is converted to electrical energy inside the generator. This electricity can then be used to power various appliances and equipment inside a boat. From fishing boats to yachts; marine generators have a large application area.Marine generators are designed to survive the harsh and wet environment of the boat. This requires different design techniques on the outside and alternative components on the inside. Many marine generators may utilize hydraulic pump systems, use more durable material, and have other features that make them more efficient for life on a boat.
