When the gas fired thermal oil boiler is running, the high temperature flame generated by the burner ignition enters the inner coil tube to form a radiant heating surface, and rotates 180° forward through the back of the inner coil tube to enter the sandwich area of the inner and outer tubes to form a convective heating surface. Then the upper part of the interlayer enters the second interlayer area of the middle and outer coils, and the atmosphere is discharged into the chimney at the back of the second interlayer area. YYQW type gas boilers has low pressure, high temperature working characteristics, its heating temperature can reach 340℃ liquid phase or 400℃ vapor phase.
Gas thermal oil boiler can obtain low pressure and high temperature hot medium when running, convenient adjustment, uniform heating, can meet the higher process temperature. This series of heat conduction oil boiler liquid circulation heating, no condensing heat loss, heating system thermal efficiency is high. The change of volume caused by heating and releasing heat of working medium and temperature rise and fall shall be compensated by technical measures in the system. There are technical measures to strictly control the content of air, moisture and other low volatiles in the working medium before circulating heating.
YYQW type gas boilers can carry on the high precision control work to the medium running. The system has high heat utilization rate, because the module is installed as a whole, the operation and maintenance is convenient, it is a kind of safe, efficient, energy-saving ideal heating equipment. The main engine installation should be in place on the basis of alignment and fixed. Please refer to the “Equipment Arrangement Reference Drawing” in the factory document for the installation orientation of the furnace body, which should be based on pipeline layout, observation of field instruments and easy operation and use.
Gas fired thermal oil boiler flue gas three return, medium flows through the inner and outer coil tube, the flow rate is uniform, safe and stable operation. Sufficient output, reasonable heating surface layout, large area, good heat transfer effect, high efficiency. Perfect automatic control measures, precise control of oil temperature, medium temperature, pressure and over smoke temperature set multiple control protection, to ensure safe and reliable operation. Automatic control level leading boiler controller using high quality electrical components, reliable performance.
YYQW type gas boilers has strong adaptability to different fuels, diversified grate structure and large diameter combustion chamber. The boiler has sufficient fuel combustion space, complete combustion and high thermal efficiency. And in the furnace body, outer spiral coil is made of multi-head, small pipe diameter steel pipe, coil has good thermal expansion performance, low stress, safety and reliability. Zozen Boilers specializes in producing high quality boiler products, has been dedicated to manufacturing high quality boiler and pressure vessel for many years, has been praised and trusted by users.
