Corrugated Tube Oil Fired Hot Water Boiler For Sauna Hot Water Using
The hot water boiler can be widely used for Sauna hot water usage,WNS series hot water boiler is a type of eco-friendly, working steady, easily adjustment, enough steam pressure, high thermal efficiency, fuel adaptable, easy to install.
Customer case
2.8MW gas fired hot water boiler exported to Kazakhstan in 2017. Our customer use the boiler for the Sauna business, generally for the shower and hot spring usage.
Boiler Introduction
This boiler is horizontal type, fire tube,three pass shell boiler. It can burn heavy oil,light oil,city gas,natural gas,lpg,lng,cng(depend on the burner selected). Boiler furnace is corrugated furnace,burning under positive pressure,fully automatic control.
1. The spiral furnace design
Increase the overall strength of the furnace,make compensation for the heat exchange and shrinkage automatically,avoid the in-perfection of welded sew crack due to the change of tube plate heating stress.Therefore,boiler has strong adaptability about various of fuel,for example,heavy oil,light oil,natural gas,city gas.
2. Improve heat transfer technology
Apply the technology of heat transfer from “the light of Harbin institute”.Adopt the design of efficient heat transfer screw thread pipe and optimize the smoke speed.The output and heat efficiency of boiler don’t decrease with the extend of operation time,thus achieve a compact structure with 10% overload capacity.
3. Climate compensation, on-demand heating technology
Considering to the outside temperature and users’ heat demand,boilers could control the water temperature in the support of heat source efficiency automatically so that we achieve the goal of on-demand heating and energy-saving heating.
