Operation of coal-based heat energy enterprises results in polluting the air with gases and dust. The evolution of heating systems by building CHP blocks reduces the negative environmental impact. Cogeneration devices powered by natural gas enable the simultaneous production of heat and electricity. This leads to smaller needs for energy from conventional sources and thus contributes to reducing the amount of burned coal and the emission of harmful substances, especially CO2 and dusts, into the atmosphere. The produced heat is transported to the existing heating system, while the energy can either be used for the business’ own needs or sold to the external network. As a result, costs of functioning become lower and new possibilities of obtaining heat recipients are created. The company’s competitiveness increases and, due to investing in advanced technologies, it is perceived as innovative and modern.
For this task, a construction project was drawn up along with all the necessary documents, including a construction permit, based on two cogeneration aggregates with total heat output of 4.6 MW and electrical power of 4.6 MW. A building with specially dedicated installation was designed, taking into account the high demands associated with noise levels legally approved for buildings located in the city centre.
Specifically, the project included:
Additionally, the contract included the verification of the legal status of the plots
of land associated with the investment and the terms and conditions of connecting
to power and gas networks.
The nominal power of the thermal network before the investment was about 50 MW (coal-based technology). The system is designed to generate warm water for general use during summer and supply the functioning of existing boilers in winter.
Within the task, complete construction and executive projects were made, based on the installation of four CHP units powered by natural gas, with total heat output of 2.6 MW and electrical power of 2.1 MW.
During the process, various documents were drawn up and obtained for the investor, including for example:
A multi-sector project concerning the modernisation of the municipal heating plant in Wołomin by building a high-efficiency cogeneration system that would produce coupled electricity and heat on the basis of two systems with gas engines of about 2 MW heat output and about 2MW electrical power each, with the possibility to install additional CHP systems with the total power of about 4MW.
The subject of this project was an architectural and structural design of a thermal power plant building, a heat accumulator and ground hardening for the construction of high-efficiency CHP systems based on natural gas in the municipal heating plant in Wołomin.
The tasks included the preparation of:
The nominal power of the heating system before the investment was about 15 MW (gas and coal technology). The aggregate will serve as a high-efficiency cogeneration source, which, during summer, will be the main heat source for supplying the heating grid with warm water. During winter, the aggregate will cooperate serially with the two existing gas cauldrons (which constitute the main heat supply during the heating season), regardless of the required heat system parameters.
Within the task, complete construction and executive projects were made, based on the installation of a CHP unit powered by natural gas, with total heat output of 2.6 MW and electrical power of 2.7 MW.
The tasks included:
The nominal power of the heating system before the investment was about 67 MW (coal-based technology).
A two-variant proposal was made for the CHP system with a total heat output of about 10 MW.
The proposal included:
