NTZMK
Specialists at the NTZMK plant (part of the NEC Group) have manufactured and assembled a fragment of a bypass chimney in one of the workshop spans: the product exactly replicated its design position. The successful completion of the operation confirmed that the structure is ready for shipment and installation.
After the test assembly, the large‑sized structure will be disassembled again and shipped to the customer. In addition to chimney metal structures, NTZMK is manufacturing lattice and solid‑wall columns for the main frame for Almaty CHPP‑3. In total, under the contract, the enterprise will supply the customer with over 2.7 thousand tonnes of products required for the construction of key facilities at the combined heat and power plant.
The modernisation of CHPP‑3, which was built back in 1962, is driven by critical equipment wear and insufficient efficiency of the existing capacities. The project envisages creating a power facility with increased capacity and manoeuvrability indicators.
The new CHPP‑3 will operate on a combined cycle: generating both electrical and thermal energy. The key technological solution of the project will be the replacement of outdated pulverised coal equipment with modern combined‑cycle gas turbine units with a capacity of up to 450 MW, running on natural gas. A full transition of the plant from coal to gas will significantly improve the environmental performance of production and minimise the impact on the region’s environment. The commissioning of the new CHPP‑3 is scheduled for 2026.

At the final technological stage, we have verified that the bypass chimney fully complies with all design requirements. This will help avoid unforeseen issues and delays at the installation site.
