What to look for when buying a coal stove

The coal-burning chambers of stoves should be lined with refractory bricks to maintain temperature, while the heat-dissipating area should be brick-free. Stoves should be designed for top-loading with high-volatility coals (10 or higher). The primary air supply that enables coal combustion must be adjustable to ensure the desired room temperature is maintained. The stove must be designed so that the primary air flows upward through the coal bed. Under all combustion conditions, no visible pollutants should be emitted from the chimney,

All flaps on the stove must be sealed with heat-resistant, non-flammable, and durable gaskets to prevent air leakage, A mechanism must be in place to prevent the chimney damper from closing completely, High-temperature-resistant gaskets must be properly installed, and it must be guaranteed that no air leaks when the stove flaps are closed, Efficiency must remain consistent across all combustion rates and with any type of solid fuel; the grate must be made of chromium-alloyed iron; the stove’s body must be constructed from cast iron with a minimum wall thickness of 5 mm or steel plate, Under all operating conditions, dust emissions from the chimney must not exceed 20% opacity. The manufacturer must provide a manual specifying where and how the stove should be installed in homes.
