Analysis of factors affecting the heat loss of the fuel gas steam generator

Fuel gas steam generators are all devices that generate steam by heating natural water or liquefied gas as a fuel to heat the water and turn the water into steam. However, from the technical level of the national standard, the fuel gas steam generator and the fuel gas steam boiler are not the same. Just in life, people have become accustomed to calling steam-generating equipment as a boiler. In some manufacturers? In order to more accurately locate their own business, the definition of the steam generator was created.

Features of the fuel gas steam generator:

1. The fuel gas steam generator is exempt from inspection, free of charge, annual inspection, and installation free.

2, the installation and commissioning is completed, the site is connected: water, electricity and fuel can be operated normally, safe, convenient, energy-saving and stable.

3, using 3 minutes to quickly generate steam, the steam production is fast, with the advantages that conventional steam boilers can't match.

4, using intelligent control system, one-button start without special personnel on-duty; with automatic water supply, automatic start and stop, fault alarm, multiple interlock protection alarm and other functions.

5. It adopts the combined structure of the tube and tube, which has the advantages of large heating area, uniform heating and high purity of steam.

There are three main factors affecting the heat loss of the fuel gas steam generator:

Smoke exhaust; exhaust gas temperature; and combustible gas and carbon particles contained in the flue gas. The amount of smoke is mainly determined by the value of excess air. If there is more excess air, the amount of smoke is higher. Otherwise, the amount of smoke is small. The greater the amount of smoke, the greater the heat loss. Therefore, as long as the excess air ratio is adjusted, the amount of smoke can be controlled within a good range. For the exhaust gas temperature, the purpose of reducing the exhaust gas temperature can be achieved by increasing the economizer, the air preheater and the like, and the amount of the exhaust gas also affects the exhaust gas temperature. However, the temperature of the exhaust gas is not as low as possible. This is because the flue gas contains some acid gases such as SO2. If the temperature is too low, they will form an acid mist. Condensation adheres to the chimney wall and corrodes the chimney, causing heavy losses. Therefore, the exhaust gas temperature should not be too low, in general, it should be greater than 160 °C. The combustible gas and carbon particles contained in the flue gas are caused by poor combustion of the fuel in the furnace. As long as the combustion state of the fuel in the furnace is adjusted, the combustible gas and carbon particles contained in the flue gas will be reduced to a low limit.
