Principle of SZL Coal-fired Steam Boiler & Hot Water Boiler
RUNLI SZL series packed water-tube steam and hot-water boiler is the double-cylinder, water-tube assembly, chain grate boiler.
Two cylinders are laid at the upper and lower level of boiler longitudinally along
The center. Front section of the upper cylinder and water all tubes at sides form
The radiant heating surface in the hearth, while the near section and tube nest in
The lower cylinder serve as convection heating surface. Coal economizer is installed
At the rear of boiler. After some heat of the combustiongenerated high temperature
Fume is absorbed by the hearth, the fume flows to the convection heating surface
Through cooling chamber and exhausts outside through the chimney via coal economizer,
Dust collector and drought fan.

Features of SZL Steam Boiler & Hot Water Boiler
1. Compact structure, small installation space, single-floor boiler room, cost-effective infrastructure.
2. Great assembly level, short installation period and inexpensive installation.
3. Sufficient and reasonable heating surface, quick temperature/pressure-rise of boiler, satisfactory productivity and high heating efficiency.
4. Introduce the air with air distribution chambers of grate. All air distribution
Chambers can adjust the air flow independently and grate can be regulated step-less speed.
5. Wide range of applicable coals and full combustion.
6. Electric control cabinet is equipped with complete automatic control and monitor
Instruments featuring high automation, safety, reliability and simple operation.
