SZL Coal boiler Introduction
SZL series shop assemble chain grate boiler is developed by ZG Boiler independently based on the features of field assemble boiler arch. SZL series assemble chain grate boiler fuses water-cooled arch technology and membrane water wall technology, which is domestic initiative. And the boilers overload capacity is strong and has wide adaptability of coal, so it has the world advanced level. With water-cooling arch and membrane water-cooling wall, this SZL boiler is more energy-saving and environmental friendly.
