In most cases, the gas generator differs little from generator installations on liquid fuel. Here the same types of electrical single -phase or three -phase generators drive are driven by internal combustion engines. Power plants of gas generators can consume various types of combustible gases, such as propane, natural gas, butane and some others, as well as have a combined power system with the possibility of gas supply or diesel fuel.
Small gas generators and power plants with a capacity of up to 3 kW are used mainly as reserve power sources in houses, cottages, at retail outlets. Thanks to mobility and small dimensions, such devices can be easily transported to the right place. They are suitable for powering a small number of electrical devices and certain types of power tools with limited electricity consumption and usually have a single -phase output with a voltage of 220 volts.
More powerful, compact generators up to 10 kW are popular in reserve schemes of small companies and institutions, life support and healthcare facilities, for power supply of cottages and private houses with a large number of energy consumers. Such gas generators are suitable for racks, for powering a sufficiently powerful power tool and equipment. It is possible to use both single -phase and three -phase 220 and 380 volts, respectively.
Gas generators, as a rule, are somewhat more expensive than gasoline options, however, the relatively low cost of fuel and the ability of some models to use both cylinder and main gas, provides significant savings in the means, the price of a gas generator depends on its size and power. It should also be borne in mind that due to the small content of harmful substances in the exhaust gases, such generators have a minimum effect on the environmental situation at the installation site.
