Natural Circulation DZL Biomas Steam Hot Water Boiler Heating System For Greenhouses
DZL series chain grate coal fired steam boiler is designed with single drum boiler with fire tube and water pipe. It has fast heat conduction and steam pressure rise quickly. It can adapt to various kinds of coal with compact structure and high thermal efficiency. This series of boilers adopt the latest science and technology such as arched tube sheet and spiral corrugated smoke pipe, which effectively improves the overall efficiency of the boiler, and prevents the occurrence of grate coking, tube sheet leakage and other failures.
