SZL chain grate coal-fired boiler has the advantages of high efficiency, strong overload capacity and wide adaptability of coal type. The boiler is mainly composed of upper and lower drum, convection tube bundle, water wall tube,downcomer and header. The upper and lower drum are arranged longitudinally. The combustion equipment is chain grate with stepless speed change device. The boiler body is composed of vertical upper and lower drum and convection tube bundle. A water-cooled wall is arranged around the combustion chamber to absorb the radiant heat of the furnace. A dense convection tube bundle is arranged between the upper and lower drum at the rear. After the high temperature flue gas after combustion scours the convection heating surface horizontally, it is led to the separately arranged economizer, and finally enters the dust remover and is discharged through the chimney. The left and right sides of the body are full membrane water-cooled wall structure, the boiler has good sealing performance and small heat loss, so as to ensure the safe and efficient operation of the boiler.
Application fields: thermal power company, textile factory, chemical factory, food factory, pharmaceutical factory, brewery, washing factory, etc.
