Fujian Longking Co., Ltd products

The SCR flue gas denitration technology of Longking has combined the disc swirl flow technology with AIG ammonia injection technology, which can ensure ammonia/flue gas mixed more evenly. The special pneumatic regulating valve group was used to control ammonia flow, which has many advantages such as good linear regulatory, fast response, stable adjustment and good sealed performance. The advantages can ensure higher denitration efficiency and lower ammonia escape efficiency. This technology can achieve the following requirements: denitration efficiency is over 90%; ammonia escape efficiency below 2.5ppm, SO2/SO3 conversion rate below 1%.

Longking`s electric control technology has been in the leading position of the industry for more than four decades. The self-developed technologies, including power supply, high-frequency power supply, pulse power supply, three-phase power supply, inverter power supply, energy-saving optimization control system ,are widely used in many fields includin power generation,building materials,metallurgy and others.

Longking pioneered the pre-boiler environmental island technology with circular pipe conveyor as the main bodies, which offers a full set of green and economical system solution for the loading, piling up, storage and conveying of bulk materials used in industries such as electricity,metallurgy, coal, mine and so on.
