Integration of GPU into an existing boiler house. Energy springboard for industrial production.

Integration of a gas piston or gas turbine unit into an existing gas boiler house is an opportunity for combined generation of electrical and thermal energy (cogeneration) at your enterprise.

The main driver for the development of any production is energy, which in the conditions of the quasi-liberal Russian capacity market is constantly becoming more expensive. Depending on the region where the industrial facility is located, the price of electrical energy has increased by 10-15% since the beginning of 2021. The need to reduce production costs or expand production puts enterprises in a difficult economic situation: on the one hand, refusal to develop threatens to reduce gross profit and reduce the competitiveness of the product; on the other hand, any increase in installed capacity requires additional energy resources, the proportion of which per unit of production grows following the volume of production. The solution to the problem is to reduce energy costs.

The current volumes of natural gas consumption for heating or technology at most Russian enterprises have decreased significantly compared to the consumption volumes of the Soviet period, often due to a decrease in production volumes. However, the technical possibility of consuming the design gas flow remains. Modern technologies make it possible to effectively use available cubic meters of gas to simultaneously generate both thermal and electrical energy. To do this, as part of technical re-equipment or reconstruction, a gas piston or gas turbine unit is installed in the existing gas boiler house, generating electricity for its own needs. Thus, the industrial facility is switching to a fundamentally new, energy-efficient energy supply model - cogeneration.

Cogeneration – the simultaneous production of thermal and electrical energy – is an effective and economical tool for increasing the energy efficiency of production, a source of energy resources obtained, in fact, at cost.

Cogeneration allows you to optimize the costs of energy supply to an industrial facility, opens up new opportunities for production development, optimization of financial and economic indicators, increasing the profitability and investment attractiveness of the facility.

The cost of 1 kWh of electricity generated by our own gas piston power plant (GPP) is 2.2-2.5 rubles. (when burning 1 m3 of gas in a gas piston unit (GPA), we obtain 3 kW of electrical energy), which is at least 2 times lower than the current tariffs for the supply of electrical energy. In addition, recycling the heat of the gas compressor will allow you to additionally save 0.3-0.5 rubles. with 1 kWh of generated electricity. The return on capital costs for a GGE device is 2-5 years, depending on electricity consumption. If the enterprise consumes only 100 kWh of electricity, the annual savings will be 2-2.5 million rubles. The advantages of switching to an autonomous energy supply through the introduction of cogeneration technology into the functioning energy circuit of the enterprise, the transformation of the boiler house into a mini-CHP: • significant reduction in costs for energy supply to production; • the ability to regulate generation volumes depending on demand online; • no need for constant interaction with network organizations, which act, in most cases, in their own interests while ignoring the interests of the subscriber; • strengthening the energy potential of production, reducing the risks of energy shortages; • increasing the energy efficiency of the facility: implementation of the provisions outlined by Federal Law No. 261 “On energy saving and increasing energy efficiency and on introducing amendments to certain legislative acts of the Russian Federation” • increasing investment potential, simplifying the search for additional investments for expansion or technological development of production

The use of cogeneration in the energy system of an industrial facility is a big step towards a more modern, safe and energy-efficient production process. Modernization of a boiler house into a mini-CHP is a widespread practice and is actively used by the largest domestic and foreign enterprises.
