ZOZEN 15 tph SZS series steam boiler is widely applied in the printing and dyeing, nonferrous metals, chemical and other industries. The SZS series boiler is designed with longitudinal double drums and "D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
All equipment (includes boiler proper, economizer, burner, valves, instrument, electric control cabinet, chimney, water treatment, soft water tank, energy-saving circulating pump, raw water pump, deaerator, etc.) is designed to be installed on one or two prepared concrete bases. Skid mounted boiler has all interconnecting piping completed and has passed the cold state test at the factory before delivery. After the boiler arrives at the site, it only needs to be connected to water, electricity and gas to operate.
Bolivia is the highest average altitude country in the world, local Bolivian companies have higher requirements for boilers than general boilers. As the altitude increases, the atmospheric pressure and the air density decrease accordingly, which adversely affects boiler combustion.
In view of this situation, ZOZEN technical team makes adjustments from the combustion system and exhaust system of boiler, fully considering the influence of low air pressure on boiler body design and combustion. By appropriately increasing the volume of the furnace to extend the residence time of the fuel in the furnace, and the problems of slow fuel burning speed and long burning time are solved.
