Henan present gas boiler maker companies in durban fuel ratio control and debugging problems 1.Henan gas boiler fuel ratio irrational: ejector conventional gas boiler burner, resulting in the air-fuel ratio adjustment can not maneuver. Most of the gas boiler uses a mechanical blower burner, causing the air-fuel ratio irrational factors are the following: air-fuel ratio unreasonable divided into two situations: when the excess air from time to time, there will be plenty of cold air is superfluous heating, resulting in increased energy boiler, boiler thermal efficiency decreased; when there is insufficient air, there will be incomplete combustion phenomenon, resulting in the boiler thermal efficiency. 2. Boiler factors Henan gas air-fuel ratio include: changes in ambient temperature lead to changes in air density and the density of the gas, fluctuation of gas pressure in the pipe causes the amount of gas injected into the furnace is increased or decreased, the throttle opening degree at some time after the operation offset, etc., can lead to imbalance in air-fuel ratio. These factors are always constantly changing, therefore, it is necessary to adjust the air-fuel ratio is continuous, uninterrupted. Autoregulation limitations burner: Burner simple conventional air-fuel ratio adjusting means arranged, by adjusting the air-fuel ratio mechanical linkage, environmental factors can not solve the problem of air-fuel ratio variation due to frequent fluctuations. If the air-fuel ratio imbalance, the burner is not self-diagnose and self-correction function. 3. Henan gas boiler fuel ratio control and debugging: In most cases, was observed with the naked eye are commissioning adjusting the fuel valve and the air damper opening degree of flame color and shape manually, it can not determine whether the air-fuel ratio in an optimal position. Even at the time of commissioning flue gas analyzer to adjust the air-fuel ratio is good, but due to the many changes in the external environment factors will lead to continued volatility combustion conditions, even a one-time adjustment of the air-fuel ratio accurately, but after a short time (a few hours or a few days means after), will soon air-fuel ratio imbalance.

Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast boiler maker companies in durban, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler, and is responsible for subsequent transportation, installation and commissioning work .

Mechanical cleaning using flat shovel, wire brushes, and motorized milling tube will remove scale, this method is relatively simple, simple structure used for small boiler maker companies in durbans. However, mechanical cleaning is labor intensive, ineffective cleaning, boiler easily damaged, should pay more attention in the descaling operation, and this method should not be used much.

China is now the standard content of nitrogen oxides are mainly three: 150mg / m³, 80mg / m³ and 3mg / m³. The nitrogen oxide content of the conventional gas boiler maker companies in durban is about 150mg, and emissions of 30mg and 80mg belong to a low nitrogen gas boiler. Adding "premix" combustion gas boiler technology can achieve low nitrogen emissions.
