Innovation is the fruits of their labors in a timely manner to protect them, the group also set up a patent Group, to build the company's model workers Innovation Studio. By the end of 2017, the company applied for by the State Intellectual Property in standardization work, the establishment of a patent technology management platform. Industrial enterprises wang-wang, the city industrial prosperous and strong. Fast afbc boiler bed material density threw himself into the path of innovation and intellectual development in the areas of clean fuel boilers, boiler industry forward to promote the development and enhance the overall strength of Anyang City, make yourself a contribution. Right now, fast boiler being saved enough strength, stir live a pond, in a move by chasing new road.
Gas-fired steam afbc boiler bed material density gas steam boiler is the use of a steam boiler heated by a gas burner. Vertical steam boiler combustion engine underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency of the boiler, reduce user costs; horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight 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, not only improves the strength of the heat absorption of the boiler, but also meets the needs of the thermal expansion of the heat exchange surface, scientific and rational, and durable.
The importance of regularly cleaning the first steam afbc boiler bed material density, thermal conductivity scales smaller than the steam boiler plate tens to hundreds of times. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. After scaling, will intensify the heat exchange of the heating surface. Exhaust gas temperature increase, reducing the thermal efficiency of the boiler, waste of fuel. The second is the impact of safe operation. Boiler normal operation, immediately after heating the metal transfers heat to the boiler water, the temperature difference between the two is about 30 ℃ -100 ℃. In the case of the presence of the fouling of heat transfer metal hindered, rapid temperature rise, strength is significantly decreased, resulting in overheating of the pressure receiving member is deformed to bulge or even bursting. The third is the destruction of the water cycle. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Due to poor heat transfer, steam boiler fouling, reduces the amount of evaporation of the steam boiler and the steam consumption. If you reduce scaling in the pipes, increasing the flow resistance of the water cycle, when serious water, the water will be completely blocked, normal circulation will be destroyed, causing water explosion. The fourth is to shorten the life of the boiler. Steam boiler heating surface fouling difficult to eliminate, especially heating surface fouling. Require frequent stops furnace cleaning, increase maintenance costs. The most commonly used method of mechanical cleaning and descaling chemical descaling, these methods will cause damage to the heating surface steam boiler, shorten the life of the boiler.
