2.8 MW Coal and Wood Hot Water Boiler for Residential Heating in Kazakhstan
For a residential heating project in Kazakhstan, the customer needed winter hot-water supply, a choice of coal or firewood, and a boiler package intended to reduce on-site assembly work. JINHONG supplied one 2.8 MW hand-fired atmospheric hot-water boiler and the associated circulation, combustion-air and flue-gas equipment. JINHONG engineers provided on-site installation, commissioning and training. The project was completed in 2026.
Customer Requirements
Residential heating required a complete system, not only a boiler body
The customer’s requirement was space heating for residential buildings. The specified boiler duty was 2.8 MW of thermal output, with rated supply and return water temperatures of 95/70°C. Continuous heat supply during the winter heating season was a central requirement.
Fuel availability also mattered. The customer wanted to use either coal or firewood rather than depend on a single solid fuel. Alongside that choice, the project needed practical arrangements for ash removal, cleaning and routine maintenance.
The customer also wanted to limit overseas site assembly. A packaged boiler and a defined auxiliary-equipment scope would simplify the equipment interfaces the installation team needed to coordinate. Low-temperature conditions and freeze-risk management were part of the customer’s operating requirements.
JINHONG Solution
A hand-fired CDZH heating package for coal or firewood
JINHONG supplied a horizontal, single-drum atmospheric hot-water boiler with packaged water/fire-tube construction. The project uses manual fuel charging, with both coal and firewood within the specified fuel capability. The hand-fired arrangement requires operators to manage fuel charging as part of routine boiler operation.
The supplied package extends beyond combustion. It includes the circulation pump, forced-draft and induced-draft fans, dust collector, flue-gas ducting, chimney, electrical control cabinet, and venting and expansion equipment. Bringing these items into the same supply scope addressed the customer’s need to coordinate the boiler with the water and flue-gas systems.
