Introduction
Natural Gas/Diesel/LPG/Biogas/Bunker/Dual Fuel Boiler
Yuanda Boiler aim to offer efficient and energy-saving gas/oil fired boilers to provide steam or hot water for factory production.
It is favored by users for its thermal efficiency ＞98.8%, high quality and environmental protection.
WNS gas/oil boiler adopts horizontal fire tube structure, which can provide larger steam/water output. It has the following advantages:
* 3-pass wet back reverse flame chamber;
* Fuel saving with economizer;
* Larger "steam-water" space with steam separator, high steam quality;
* Packaged boiler design, easy installation;
* Automated operation by PLC and safety functions such as water level, pressure and temperature monitoring;
* Equipped with international first-class brands burners and valves.
LHS vertical gas/oil fired boiler have smaller capacity (0.1-2ton,100-2000kg,99-1400kw), a kind of fast-heating packaged boiler.
It adopts up-standing vertical structure, small in size, space-saving, occupies less footprint; no need to build boiler room, reduce cost and high flexibility; Simple structure, fast start and stop; lower thermal efficiency than horizontal boiler.
