LPG thermal oil boilers fuel oil (gas) by the burner ignition generated after the high temperature flame into the inner tube to form a radiation heating surface. Through the back of the inner coil, it rotates 180° forward and enters the interlayer area of the inner and outer tubes to form a convection heating surface. Then in the upper part of the sandwich into the middle and outer coil of the second sandwich area, in the second sandwich area back to the chimney into the atmosphere. Gas-fired thermal oil boiler has the characteristics of high working temperature under low pressure and high precision control of medium operation.
The series thermal oil boiler adopts horizontal structure and combustion mode is chamber combustion. The heating surface of the furnace body adopts inner and outer coils, and the pipe ring is about 30 rings. The pipe size is φ57×3, and the inner and outer rings are connected in series together. The heat carrier enters the inner coil from the outer coil and then flows into the service system. YYQW series boiler inner and outer coils are PN16, DN50 specifications, made of φ57×3 tubes, the material is 20(GB/T3087-2008). Boiler thermometer interface, pressure gauge interface adopts DN15 interface, nozzle adopts φ22×4.
The main engine of LPG thermal oil boilers is packaged with the body, the inner body is the boiler body, and the outer body is the insulation layer. YYQW series thermal oil boiler system has high utilization rate, convenient operation and maintenance, perfect control system, and energy saving, environmental protection, safety, is the ideal heating equipment at present. At the same time, the boiler also has the advantages of convenient installation, as long as the upper body and the lower combustion chamber are closed, and the installation cycle is short. The heating surface of this type of boiler adopts close row disk tube, and the heating surface is arranged enough to reduce the heat load on the tube surface and make the heat conduction oil safer to use.
Gas thermal oil boiler medium process is reasonable, thermal oil from low (import) to (export), the gas generated in operation, better improve the thermal efficiency of the boiler. Boiler fuel in the combustion chamber for adiabatic combustion, can make combustion ignition easier, combustion more fully, better improve the thermal efficiency of the passage. The top of the boiler is arranged with dense coil tube, which can better protect the top and avoid the phenomenon of burning out the top. When the boiler leaves the factory, the body, oil storage tank, oil and gas separator, filter circulating pump, injection pump, valve, instrument, electrical control cabinet and other parts are transported as a whole.
LPG thermal oil boilers saves energy, has high thermal efficiency and good economy. Thermal oil boiler will appear in the process of system operating pressure from high to low, if the heat conduction oil boiler import and export pressure difference is bigger, it is possible that by-pass opened entirely, practice more than once appear after bypass opened entirely, the boiler inlet pressure to the pump at full capacity, and export pressure is small, this kind of situation, Generally adjust the bypass valve can be removed.
