In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired boilers waste heat boilers for hydrogen plants nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas steam boilers for low-nitrogen emissions transformation.

The sum of the concentrations of Ca2 and Mg2 in water is called the hardness of water. It is clearly stipulated in the regulation of boilers waste heat boilers for hydrogen plants supervision that the hardness of boiler water is ≤ 0.03mmol/L.Ca2 and the Mg2 is distributed in water in the form of ions, even if the water is softened, there are still some sulfate ion and bicarbonate ion in the water. Because bicarbonate ions are always dissociated in water, i.e.: HCO3-A→H++CO32-(1). Although the dissociation is very weak in this process, the dissociation is strengthened due to the (2), (3) reaction. Then, in boiler operation, there are always conditions for the formation of insoluble substances: Ca2++CO32--CaCO3(2). Mg2++CO32-→MgCO3+(3)

Steam boilers waste heat boilers for hydrogen plants filled with water accident hazards and some questions to resolve: a steam boiler in the boiler, which in the specific knowledge to explain, the following will be carried out, were summarized, then for: specific hazards full of water accidents steam boilers, as well as a steam boiler feedwater, What are the main requirements? In addition, there are other related issues. So then, we will soon be answering these questions, so that we can clearly understand. 1. Specific hazards steam boiler full of water accidents, if the phenomena steam boiler full of water, then this in terms of a boiler is a very big impact, as well as adverse consequences. The specific terms, it is as follows: a steam boiler full of water, then it will bring a lot of water vapor, or steam pipe water hammer phenomenon, thereby reducing steam products. And, it will affect the normal supply of the boiler and so on. In addition, the consequences are very serious, it is for the steam boiler superheater fouling, resulting in damage to the boiler and so on. 2. Effect of a steam boiler feedwater requirements of the superheater for steam boilers, in which the feed water flow requirements to: feedwater hardness should be less than 0.03mmol / liter. And, in order to avoid the phenomenon of the boiler. Then, in the standard, should be strictly in accordance with the requirements to carry out specific operations in this area. In the boiler, superheater, then if there is, it is capable of producing dry steam. However, if the deterioration of kerosene, then only will the saturated steam.
