The SZL series biomass-fired boiler is a chain grate water tube boiler designed by ZOZEN Boiler based on advanced international technology and experience. It features a horizontal double-drum and vertical layout structure. The boiler consists of two major parts: the upper part is the heating surface and the lower part is the combustion equipment. The front of the boiler body is surrounded by water-cooled walls. The upper part is connected with drum and the lower part is connected with the header to form the combustion chamber, absorbing the radiation heat of the furnace. At the rear end, a convection tube bundle is arranged between the upper and lower drums. After the fuel is burned in the furnace, the high-temperature flue gas is swept across the convection tube bundle for the secondary return, then guided to a separately arranged economizer and finally enters the dust collector before being discharged through the chimney.
The corner tube boiler is a compact and efficient boiler that utilizes a pipe system as its skeleton. It features a fully enclosed membrane wall structure, flag tube design for the convective heating surface, and is widely used due to its compact structure and rapid temperature rise. It is a bulk-structured boiler.
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.
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.

The YQW series oil/gas thermal oil boiler adopts a two or three passes round coil structure. The end of the coil tube is tapered, effectively protecting the end furnace wall of the boiler. It is equipped with advanced combustion equipment, and the operation of the boiler is fully automated. The boiler is shipped as a whole and can be put into operation just by connecting the gas (oil) and electricity after it is in place on the site.
The YLW series thermal oil heater, with its horizontal layout and square coil tube design, uses a chain grate system for efficient fuel combustion. It incorporates mechanical features for solid fuel feeding, ventilation, and slag removal. During operation, fuel undergoes radiation and convection heat exchanges, proceeds to the waste heat boiler, and subsequently moves to the air preheater and dust remover. The remaining flue gas is then expelled into the atmosphere, resulting in optimal heat transfer and efficient industrial heating.
