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
