Gas Three Return Hot Oil Boiler Heating Area Large Oil Temperature Control Precision

Product Description

 Overview:

YYQW series organic heat carrier furnace is a horizontal coil structure heating equipment developed and designed on the basis of imported equipment from abroad. It is mainly composed of the body and the combustion chamber. The high temperature flue gas generated by the combustion of natural gas enters the body and exchanges heat with the organic heat carrier in the coil by means of radiation heat transfer and convective heat transfer. The closed circuit forced circulation of the organic heat carrier system is realized by the circulating oil pump, and the heat carrier obtained in the body serves as the heat source to supply the heat equipment.

 the main characteristics of the boiler:

(1) Large heating area, fast heating and pressure boost;
(2) Organic heat carrier volume is small, start fast;
(3), fast assembly factory, short installation period, put into operation fast;
(4) Compact structure, small footprint, provincial infrastructure investment.

 Brief introduction of the main structure:

(1) The boiler is a horizontal coil structure, composed of two parts: the boiler body and the combustion chamber;
(2) The boiler adopts coil structure, and the inner and outer coils are made of seamless steel tubes for the boiler;
(3) After the top of the coil is poured, the combustion chamber is formed;
(4) The thermal insulation layer is made of materials with small thermal conductivity, and the furnace wall is made of lightweight concrete, which reduces the loss of q5 and reduces the dead weight of the boiler;
(5) The use of non-embroidered steel plate packaging, both firm and beautiful.

Working process:

After gas combustion, the high temperature flue gas radiates heat through the inner coil, folds into the inner and outer coil interlayer from the upper part of the inner coil, absorbs heat by the interlayer convection, turns to the outside of the outer coil at the lower part of the outer coil to fully transfer heat, leaves the boiler after three return trips, and is discharged into the atmosphere through the chimney.
