What structure and principles of industrial boiler feed water pump prices in particular? What structure and principles of industrial boilers in particular? Industrial boilers has become the hottest on the market boiler boiler. Whether it is gas or gas hot water boiler steam boilers, gas boilers generally use natural gas, liquefied petroleum gas and city gas as a fuel gas fuel. First, the working principle of gas steam boiler: the furnace and the combustion heat of the fuel gas steam boiler, heating pot of water evaporated into steam. Water pan (drum) in the furnace gases are fuel combustion energy released continuously heated, increasing the temperature and pressure steam is generated. When the boiling point of water increases with increased pressure, is sealed pot, the pot water vapor expansion is limited, and therefore the thermodynamic pressure (strictly speaking, water steam boiler). It is widely used as an energy source in the drum, the water is heated and vaporized again to saturation. Second, gas steam boiler basic structure: gas steam boilers and boiler drum consists of two body parts protection, instrumentation equipment, automatic control and protection system of continuous safe operation of its composition. This boiler water wall boiler drum boiler drum in the zoning arrangement, the first two return pipe fireworks smog chamber back to the drum. Connected between the drum and the tank, with water-cooling pipe and the downcomer, which constitute the framework of the combustion chamber. The pot is provided at the top with a steam water separator, to reduce the amount of water extracted from the steam. The bottom of the pan heating surface of the drum, and fireworks waterwall tubes.
Excessive air in the boiler furnace will affect the furnace combustion. Therefore, how to effectively control the air excess coefficient is one of the prerequisites for ensuring the reasonable operation of the boiler. Today, we will explain the excess air in the gas boiler with high degree of automation as an example: Furnace air excess coefficient is one of the important indicators to control the combustion process of gas boiler furnace. For the layer furnace, the air excess coefficient at the exit of the furnace is generally between 1.3 and 1.5. According to the air leakage of each flue section of the flue gas, the air excess coefficient of the exhaust should be 1.8-2.0. There are three factors that determine the heat loss of smoke exhaust: exhaust gas temperature, air excess coefficient and cold air temperature. Among them, the air excess coefficient of gas boilers is the main influencing factor. Excessive air excess factor is a great waste. A large amount of cold air enters the furnace, firstly reducing the furnace temperature, the combustion conditions tend to be unstable, and the volume of the flue gas is increased, and the heat loss of the exhaust gas is increased. Calculations show that when the air excess factor is increased from 2.0 to 3.0, the exhaust heat loss increases to 4.5%. At the same time, the burden of the blasting fan is increased, and the power consumption is increased. In order to improve the thermal efficiency of gas boilers, it is necessary to pay attention to and improve the understanding of the serious hazard caused by excessive air excess coefficient, and strictly control the air excess coefficient in combustion regulation, which is a field often overlooked in the heating industry.
