DALGAKIRAN Gas Generators

Dalgakiran gas reciprocating generators are a reliable solution for power supply to industrial and domestic consumers, as well as critical social infrastructure facilities. Electric generators from Dalgakiran, operating on natural and liquefied gas, are used for constant and backup power supply, and our cogeneration units not only provide electricity but also heat.

The relatively low cost of gas, low emissions of harmful substances during its combustion, the ability to power the generator from the gas main, and the option of cogeneration ensure the popularity of gas piston plants in the Ukrainian power generator market.

The gas-fired power generators offered by our company can be divided into 4 types:

• power plants designed to operate continuously as the main source of electricity;
• backup generators;
• cogeneration units (the main source of electricity);
• power generators running on liquefied natural gas.

The first three types of equipment use mainstream natural gas (methane) as fuel. The fourth type of unit runs on liquefied propane-butane.

Generators for continuous operation

These gas generators are designed for long-term continuous operation as the main, sole source of power supply. This requires high wear resistance. It is provided by components from leading global manufacturers. Dalgakiran gas-fired power generators use exclusively reliable engines from Perkins (UK), MAN, Liebherr (Germany) and alternators from Leroy-Somer (France).

“Main gas” is an ideal fuel for such purposes, as it is continuously supplied to the gas generator for continuous use . There is no need for large fuel tanks and storage facilities, and the problem of fuel delivery is eliminated, which ultimately reduces operating costs.

Generators for backup power supply

A gas generator with automatic start-up to ensure power supply to the facility in case of failure of the main power source. On average, accidents are eliminated within one day, up to three days. The cost of such equipment is much lower, as it does not require 24/7 operation.

Less commonly, such gas-fired power generators can be used to cover short consumption peaks when there may be a power shortage. Sometimes, due to the technical capabilities of local power grids, an enterprise is unable to provide the necessary power for production. Most often, this situation occurs in the agricultural sector and is seasonal.

Such generators are mainly used for engines:

• SCANIA (Sweden) – with a capacity of 300 kW and above;
• DOOSAN (South Korea) – with a capacity of 100 to 300 kW;
• SDEC (Shanghai Diesel Engine Co, China) – with a capacity of 100 to 150 kW;
• LOVOL (China) and YAVUZ (Turkey) – with a capacity of up to 90 kW.

Cogeneration units

Natural gas-fired cogeneration units not only provide electricity to the facility, but also transfer heat to the heating and hot water supply system. Technically, such a system is a gas-fired power generator with a heat exchange system. Given that the efficiency of power generation is about 40%, up to 60% of the energy from gas combustion is used to generate heat. Thanks to heat exchangers, it is possible to transfer a significant part of the heat energy to the heating system or hot water supply. For example, with 300 kW of electricity generated by the plant, we receive about 400 kW of heat energy.

Gas power generators on liquefied gas

This type of plant uses liquefied propane-butane gas rather than methane gas as fuel. While methane-fired plants require a gas pipeline, a liquefied gas-fired power generator requires gas cylinder equipment.

The main advantage of such installations is that they can be used where there is no possibility of a gas pipeline or it would not be financially justified.

Why is it worth using gas generators?

Unlike its diesel and LPG counterparts, a generator running on main gas does not have any difficulties with refueling and storing fuel.

A diesel generator set, even with an enlarged tank and if there is an on-site diesel fuel storage facility, will not be able to provide such a long continuous operation. In addition, fuel delivery costs are inevitable.

For gas cylinder generators, the cost of maintenance is more expensive not only due to the need for space for their placement, transportation and refueling costs. The gas cylinders themselves require much more attention – malfunctioning valves, cracks and corrosion of the casing must not be allowed. The maintenance and servicing of LPG systems is regulated by the “Rules for Occupational Safety and Health during the Operation of Pressure Equipment”.

How to choose a gas power generator?

The principle of equipment selection is similar to the choice of a diesel generator set. Let’s take a closer look.

Power of the gas generator

The main or rated power is the maximum power output at a variable load for an unlimited operating time. The load should not exceed 70% of this capacity during 250 hours of continuous operation. An electric generator should not operate at 100% of its basic capacity for more than 500 hours per year.

As for the overload, it should not exceed +10% in one hour for 12 hours of continuous operation.

Number of phases and voltage

1-phase gas generators are produced only for low power, most of the equipment presented in our company is 3-phase.

Equipment class and additional options

As mentioned above, we offer 4 types of gas generators, and with equal power, they have a number of technical differences. For the correct selection of equipment, it is important for our specialists to know in which mode the gas power plant is planned to be operated and what conditions are available for this. In addition, the client may need additional options, such as remote monitoring and control of equipment.

Type of fuel

Main gas or LPG. Everything is simple here – the choice depends on the possibility or impossibility of supplying a gas main. It should be borne in mind that liquefied gas installations from Dalgakiran are limited to a capacity of 300 kVA.

Installation and connection of gas generators

The first thing to note is that the installation of a reciprocating gas power generator cannot be done independently and unauthorizedly. This requires a technical specification, a permit and a contract with a gas supplier. You can consult our specialists on this procedure by contacting us in any way convenient for you.

Installation of DALGAKIRAN gas-powered generators outside the premises is similar to that of diesel generators. The main difference lies in the gas supply line. Since the power plants are supplied in protective noise-insulating enclosures, the manufacturer has already provided protection against precipitation. If necessary, a protective fence can be supplied and an additional precipitation canopy can be installed.

Indoor installation imposes additional installation requirements. Depending on the capacity of the unit, free space, forced ventilation, fire safety and exhaust gas removal systems must be provided.
