When the burner is started, to be good conditioning into the wind, the use of the air-intake amount not large, nor small, the share of fuel and air control at a reasonable scale, natural gas is abundant burning, gas steam boiler flue gas temperature useful to decline, so the smoke gas away the heat loss is also reduced, to the extent it is bound to progress on the utilization of geothermal energy.
The inner parts of the pot include steam-water separation and steam cleaning, water distribution pipe, sewerage and dosing equipment, etc. The function of the steam separator is to separate the saturated steam from the water wall and to minimize the amount of water droplets carried in the steam. In the middle and low pressure boilers, baffles and gap baffles are commonly used as the coarse separation elements, and the boilers above the middle pressure widely use various types of cyclone separators for coarse separation, and further separation is carried out by means of shutters, wire mesh or even steam plates, etc. The drum is also equipped with water level meters, safety valves and other monitoring and protection facilities.

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.
