YLW Type of Horizontal Chain Grate Coal-fired Thermal oil Heater
• The body structure of SHENGWEI Brand horizontal square-box boiler is out of the ordinary. which adopts national patent technology with independent intellectual property rights. No dead air in the boiler tube. Convection area cannot burn air-isolated plate and the fire resistant brick on the top cannot collapse, which increase service life of boiler and heat transfer oil.
• SHENGWEI Brand square-box boiler may adopt three kinds of chain grate, i.e. :Chain belt type: with simple structure. low steel consumption, high air leakage efficient, high coal leakage volume. suitable to burn I II soft coal; Squama type: with uniform air distribution. lower coal leakage volume, running with rolling friction, low resisting force with endurance, easy and simple replacement of boiler grate, high steel consumption, and high cost, suitable to burn I II III soft coal.
• Rolling type grate: burning coal in rolling mode, with high burnout rate, thoroughly treated side-sealed air, suitable to burn II III soft coal and coal gangue.
