CGB/CGOB SERIES FUEL (GAS+OIL) STEAM (HOT WATER) BOILER

FEATURES

• 1. CGB/CGOB series automatic fuel oil and gas boiler adopts the international classic structure form. The combustion chamber adopts corrugated fumace and low position arrangement which effectively increases the heat e x change area and enhances the turbulent heat transfer of high temperature flue gas. At the same time, it can alleviate the short life of equipment caused by thermal e x pansion and contraction.
• 2. The smoke pipes of the three-return structure are arranged symmetrically to the left and right, ensuring the best condition of heat e x change area and heat transfer efficiency, all wet back arrangement, ensuring the safe operation of the boiler equipment and reducing the loss caused by maintenance.
• 3. The boiler control adopts fully automatic operation, the computer program controls the combustion automatic adjustment, the steam boiler has the function of Waler level self-control ignition and flameout, high and low water level steam overpressure automatic protection, etc. The hot water boiler has over temperature, over pressure, ultra low pressure alarm protection, etc. Function to ensure sale operation of boiler combustion.
• 4. The boiler is equipped with international advanced imported burners, which have high combustion efficiency (more than 86%). The smoke emission meets the requirements of the national environmental protection category I area (landscape protection area), regardless of various types of industrial and mining, hotels, hospitals, enterprises and enterprises. Or the shipbuilding industry, the company's products will be able to meet your needs.
