Coal-burning smoke-less power-saving normal-pressure boiler

In the improved boiler, fume is made to return and reburnt in high temperature area to release large amount of heat, the improved heat conducting structure has large heat conducting area and high heat conducting effect, and the triple folding boiler structure with slant water tank results in homogeneously distributed airflow. The high temperature furnace is separated by the water tank with insideair passage into several parts; the grate has mechanical ash eliminating function; air jet pipes in front of the grate can support burn; the slag separated by the electric sieve is re-burnt; and the boiler has automatic water feeding function. The boiler is coal saving and smoke-less and has less environmental pollution.
