ZBG offers years of experience utilizing waste gases from various industrial processes can be recovered to reduce energy consumption. Waste heat hot water boiler for sale is mainly used to generate heat and hot water by utilizing waste gases in refinery, petrochemical incinerator gases, thermal oxidizer gases, nitric acid process gases, fume incinerator gases, coking, FCC, cement kilns.

• All Waste Heat Recovery Hot Water Boilers are made with 12 gauge tubes, 3/4" tube sheets with 3/4" ligament spacing and furnaces thicker than ASME code requirements. All section I furnaces above 24" diameter are corrugated to help reduce the stresses associated with expansion and contraction.
• Waste heating recovery boiler economic lifetime can average up to 40 years
• We provide installation of the latest technology and modularized components to increase the overall efficiency of your waste heating recovery boiler and reduce maintenance. We also offer essential component upgrades and field services for recovery boilers
• Flexible arrangement, small occupation, less investment in basic construction, small amount of air leakage and low rate of consumption for steel materials

Corner tube hot water boiler is a type of natural circulation water-tube boiler which differentiates itself from other water tube boilers by its characteristic water-steam cycle and a pre-separation of heated steam from the steam-water mixture occurs outside the drum and the unheated down-comers.

• Natural Circulation Corner Tube Boilers adopt corner tube pattern, self-supporting structure, the problem relating to the expansion and the supporting of the boilers are tackled smartly. The supporting structure is stable and compact.
• The furnace and the descending fuel gas duct adopts total welding membrane water cool tubes wall structure, which has the features of good sealing, less heat lost and little pollution.
• Both the air pre-heater and the economizer adopt case pattern structure, which can ensure them be transported in package, so the installation time can be saved and seal-ability of the fuel gas duct is strengthened.
• There is flag pattern heating surface before the high temperature super heater, so the high temperature ability of the super heater can be ensured, meanwhile, the super heater can be operated in the serious fuel gas environment stably
• The cross-girder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak. And the grates are made by the first-class professional manufacture
• The fuels that natural circulation corner tube boilers use are sprayed to the furnace, which can ensure the straticulating combustion and suspending combustion, thus the combustion efficiency is enhanced
• Natural Circulation Corner Tube Boilers setting so that the total weight of the boiler is lighter

Circulating fluidized bed boilers take clean coal combustion technology, is available to burn low grade coal efficiently. Generally the fuel coal and biomass are all fit to burn in the CFB hot water boiler.

• high combustion efficiency, energy saving evidently. Boiler thermal efficiency is about 85%, 15%-20% higher than the national standard.
• energy saving circulating fluidized bed boiler has wide output adjustment range and fast regulation speed. With strong ability to adapt the load changing, load range change ratio is up to 1/3~1/4. B
• clean burning, excellent environmental performance. Circulating fluidized bed combustion temperature only around 850 ℃~ 950℃, is a low-temperature combustion.
• easy to ignite, and could press the fire for a long time.
• compact structure, low maintenance.
