Gas steam boilers have the advantages of generous appearance, compact structure, less space and convenient transportation, not only can meet the needs of industrial production, but also energy saving and environmental protection, the real realization of clean combustion and pollution-free emissions in the production process, boiler thermal efficiency can reach more than 92%. The boiler is suitable for a variety of fuels, such as natural gas, LNG (liquefied natural gas), LPG, coke oven gas, blast furnace gas, carbon black tail gas, methane and other gaseous fuels.
The industrial gas-fired boiler is mainly composed of two main bodies, the boiler shell and the furnace and the accessories, the instrument auxiliary equipment, the automatic control and the protection system to ensure its safe and economic continuous operation. This kind of boiler is a boiler drum type boiler with water cooling wall. Two return pyrotechnic tubes are arranged in the left and right partitions of the drum, and the front smoke box is turned back in the front of the drum. Between the drum and the lower box, there are water-cooled wall tubes and descending tubes, which constitute the frame of the combustion chamber. There is a soda separator on the top of the drum to reduce the water carried out by steam. The heating surface of the pot body is the lower part of the drum, the water-cooled wall pipe and the pyrotechnic pipe.
The combustion chamber of gas steam boilers adopt large volume design, which makes the combustion more fully, and the heating surface layout is optimized to the maximum extent. The structure of the furnace is corrugated, which not only increases the area of heat transfer by radiation and convection, but also meets the need of free expansion of the furnace after being radiated by high temperature. The boiler adopts the wet-back structure, the whole side pull butt weld, high reliability, low maintenance cost. The flue gas flow resistance is small; the operation power consumption is low, can save the operation cost.
The automatic controller of gas boiler detects the pressure sensor, water level power supply, fuel oil, gas and its own circuit at any time. If any problem is found, it will immediately alarm and stop the furnace for protection. The controller automatically displays the fault points and sends out an alarm sound in the machine. Gas steam boiler price level is not uniform, users in the purchase of industrial boiler is also should comprehensively consider the boiler brand, tonnage, company strength, service and other factors. ZOZEN fully meets the standards of gas boiler manufacturers, has the national boiler production class A qualification, passed the ISO9001 international quality management system certification, American Society of Mechanical Engineers boiler, pressure vessel ASME certification, and is the largest boiler manufacturer in the Midwest of China.
