Vertical gas-fired (diesel-fired) boiler, mostly used as steam boiler, hot water boiler. 

LHS boiler is vertical type low pressure (1bar-15bar) two pass fire tube boilers,  applicable to various fuels such as diesel, natural gas, and so on.  The boiler has advantages of low cost, smaller area occupied, and quick steam generation.

Core Technology: Adopt three-pass structure with top-fired burner, the flame can completely spread from the top to the bottom and burn sufficiently. The gas need to make a three pass heat transfer, so the heat loss is reduced and the thermal efficiency is higher. 

Gas/Lpg/Diesel Boiler  Advantages

1. Low pressure operation, safe and quick steam generation，vertical type, small area occupied, low investment cost

2. Adopt unique heat resistance design, big heating area, high thermal efficiency

3. Big furnace design, make sufficient combustion, high combustion efficiency

4. Multi-protection for over pressure, over temperature, water shortage, flameout to ensure the boiler saftey operation.
