Project Overview

Robust coal-fired heating boiler designed to withstand harsh winter conditions, ensuring warm homes for the community.

This project demonstrates our commitment to delivering high-efficiency, reliable heating solutions tailored to specific industrial needs. The system was designed to maximize energy efficiency while ensuring strict compliance with local environmental regulations.

Client Background

A municipal heating company in Katowice, Poland, responsible for supplying heat to a residential complex of over 3,000 households. The region has a history of coal mining and relies heavily on local coal for energy.

The Challenge

The previous boilers were technologically outdated, with low efficiency (around 60%) and heavy smoke emissions that violated strict new EU environmental standards. The client needed a solution that could still utilize accessible local coal but with drastically reduced pollution and higher efficiency.

Our Solution

We supplied a 25-ton SZL Chain Grate Coal Boiler equipped with a state-of-the-art emission control suite, including a baghouse filter and wet Flue Gas Desulfurization (FGD) unit. The boiler features a membrane water wall structure to improve heat transfer and airtightness.

Key Outcomes

Thermal efficiency jumped from 60% to 85%, significantly cutting coal consumption.
SO2 and dust emissions reduced by over 90%, fully meeting EU environmental directives.
Provided stable, 24/7 heating for 3,000 households during the harsh Polish winter.
Automated grate system reduced labor intensity and improved operational safety.
