SZS series boiler is double drums, longitudinal arranged, "D" type chamber structure. Furnace is on right side and convection tube bundle is on the left. The body is fixed on the basement by middle and both end flexible supports and make the boiler to expand horizontally to sideways. Around furnace is membrane water cooling
tube wall. Furnace and tube bundle is totally separated by the membrane water wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, bundle area, and then from left front part enters spiral fin coil economizer and condenser, finally discharged to atmosphere through chimney.
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
CFBC technology is a new, efficient, and low-pollution clean coal method. This low-temperature combustion significantly reduces Nitrogen Oxide emissions and enables direct, high-efficiency desulfurization. Economically straightforward, CFBC lowers costs compared to other methods and accommodates various fuels, including low-calorific, low-quality coal. The resulting ash is reusable, eliminating secondary pollution. Moreover, CFBC supports wide load adjustments, operating down to about 30% of full load.
The DZL series quick-installed boiler is a horizontal three-pass water-fire tube chain grate boiler designed for bituminous coal combustion. The boiler features a single drum layout with threaded smoke tubes for convective heating surface, and water-cooled walls on both sides of the drum for radiant heating surface. The combustion equipment adopts a lightweight chain grate, and the boiler is delivered in a complete quick-installed form. The electrical control system enables infinitely variable control of the grate, with alarm and interlock protection for critical parameters.
