Notes boiler blowdown and the specific steps boilers use a long time there will be all kinds of dirt, these vexing dirt may also affect the use of the boiler, the boiler should be how to clean up the dirt of it? What issues should pay attention to it? Described briefly below: 1. In order to prevent the water inside the boiler slag scale accidents caused by it, we must ensure that the internal flow of water quality, water alkalinity reduction furnace, when the furnace water alkalinity greater than 20 mEq / l, should be sewage. Note that when the sewage: 1, when two or more than two boilers use a sewage, the sewage is prohibited simultaneously. 2, if a boiler in the repair, so that the boiler should be isolated from the manifold open. 3, blowdown, the water level should the boiler at high and low loads. Second, the blowdown steps: 1, open the drain valve, preheated sewage mains, pipelines After preheating, the big valve, the discharge is completed, immediately close the drain valve. 2, blowdown, if there is an impact sound in the outfall passage, the discharge valve should be closed immediately until small sound disappears, and then slowly open the valve play, sewage for too long, the drain valve is fully opened time is generally not more than 15 seconds , so as not to affect the boiler water circulation. 3, sewage and cycle emissions should water quality monitoring personnel to determine the general sewage class at least once a regular basis. These are the boiler blowdown precautions and specific method, if it is found to be timely boiler fouling detergent treatment, if ignore them, over time, it will not only affect the efficiency of the boiler, but also a security risk.

Condensing boiler flue gas heat recovery, so that the boiler efficiency is improved, but not all areas are suitable for condensing boilers.

April 8, 2019 China International Corrugated exhibition in Shanghai New International Expo Center, such as about the opening. Fast boiler as China's "most influential brand of industrial boilers," was invited to participate in the exhibition.

Feedwater temperature decreases, the steam temperature rise but why? In order to improve the thermal efficiency of the entire power plant boiler, power plant boiler feedwater heaters are equipped, the heater previously called feed pump low pressure heater, after giving the high-pressure pump called the Heater. By high pressure feedwater heaters, water temperature greatly increased. For example, medium pressure feed water temperature of the boiler mostly heated to 172 deg.] C, typically heated to a high pressure furnace 215 ℃.
