oxygen trimming device for boiler

Both of them work with a high efficiency. Compact structure and easy installation ensure efficient, clean, economic, safe and stable oxygen trimming device for boiler operation, therefore, it is widely used as an energy-saving and environment-friendly equipment in industry.

Condensing oxygen trimming device for boiler is to adopt a new type of modern scientific research and technology - technology of condensing boiler, condensing boiler This technology will open with the traditional distinction boiler, the boiler can increase heat absorption, with high thermal efficiency to a large extent.

Low thermal load combustion of natural gas, gas-fired oxygen trimming device for boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporize into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. The fuel gas-fired steam boiler can be divided into natural gas, city gas steam boiler, a steam boiler coke oven gas, LPG and steam boiler; according to the structure can be divided into vertical and horizontal steam boiler steam boiler. Gas boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving , more economical, and a waveform furnace threaded pipe structure, i.e. increase the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.

Steam oxygen trimming device for boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

How to implement oxygen trim control - Carbon Trust

How to implement oxygen trim control Air to fuel ratio is one of the main factors affecting boiler efficiency. Although the ratio is set during commissioning, it tends to drift after a while. Oxygen trim controls ensure the ratio is always at its best, saving you around 5% on fuel costs. The business case
