Gas or Oil Fired Thermal oil boiler

1. Adopt big open door for front smoke box to achieve easy inspection and maintenance 2. Designed inspection hole in the back, can enter into the boiler furnace for internal inspection by opening the back smoke box door 3. Use wet back structure, fundamentally solve the heat conduction oil boiler smoke box after due to back to the burning room temperature through high burn out. 4. Use three return structure, not only improves the thermal efficiency of boiler, also to avoid the shell of the boiler burning deformation at high temperature. This is the biggest characteristic of the company design, other manufacturers have adopted three return, but not the third return external decorate heating surface, is dry, if user use temperature over 250 °C, the former smoke box shell easy to burn out. This is also why when we design consideration in the cause of the third ring coil. Now most companies back into the combustion chamber at the back of the design of heating surface, which is designed for the wet type, this is the cause of boiler smoke box easy to burn out after. And the smoke chamber before and after the company cannot be opened url:http://www.slboilers.com
