WNS Series Fuel Gas Steam and Hot Water Boiler

0.5-20t/h (0.7-14MW) fuel & gas, steam and hot water boiler produced by our company has an all-wet back structure and efficient heat transfer elements, and is equipped with an imported burner and full-automatic control equipment. The boiler adopts a three-pass smoke structure, namely fuel (gas) is injected into a combustion chamber for combustion through a burner; the combusted high-temperature smoke flows through a water-cooled small smoke chamber and then enters a threaded smoke tube for efficient heat transfer in the second pass; then the smoke flows through a smoke box and then enters a smoke tube in the third pass; finally, it is discharged out of the smoke box through a chimney. url:http://www.slboilers.com
