Henan gas boiler disabled corrosion prevention, mitigation methods in order to prevent or mitigate disabled corrosion protection measures should be adopted shutdown. Many Henan method gas boiler shutdown protection, mainly divided into two categories: wet and dry protection protection. Wet disable protection commonly used in the short time, for example within one month. Wet protection common method is to fill in the other peroxygen Henan gas boiler water or aqueous alkali, the holding pressure 0.3 ~ 0.5Mpa, to prevent air from leaking into the. If a longer shutdown, or cold weather, in order to prevent freezing equipment, should be protected by a dry method. After shutdown method, the temperature dropped to 70 ~ 80 ℃, the furnace was let go all the water, using waste heat of the gas boiler Henan the water in the heating surface all evaporated to dryness, and dried with compressed air without water vapor furnace all blown off, and then placed in the container-contained anhydrous calcium chloride to the drum. Per cubic meter of water volume ratio 0.5 ~ 1.0L of calcium chloride was placed (e.g., with lime according to 2kg / m3 basis), then the manhole is closed, periodically checked and found to be replaced when the desiccant into powder. Henan gas boiler can also be charged to charge ammonia or nitrogen is protected, its preparation and use as a desiccant. Since ammonia is lighter than air, so protection during charging and ammonia, the ammonia gas should enter the upper exhaust air from the lower portion. Nitrogen is slightly lighter than air, can enter the upper portion of nitrogen from the exhaust air from the lower portion. To prevent air from leaking into, the pressure should be maintained to 0.3 ~ 0.5Mpa, the pressure should be reduced to replenish ammonia or nitrogen.
Hot large capactiy water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
Before pickling, the boiler should take the representative scale samples to test and formulate the cleaning plan. The corrosion index sheet should be hung in the boiler and the acid box at the beginning of the acid injection (until the acid is removed), and the corrosion index plate shall be put into the boiler and the acid box at the beginning of the acid injection. The technological process of pickling and the temperature, concentration, flow rate and time of the pickling solution should be carried out and controlled according to the cleaning scheme, and the samples and tests should be continuously taken and recorded during the cleaning process. After cleaning, use furnace unit, cleaning unit and boiler safety supervision department to check and accept the cleaning quality.
Exhaust gas temperature of the heat loss is heat loss of a primary gas boiler, it is mainly dependent on the temperature of exhaust gas with an excess air ratio. In operation, perhaps you want to make sure that decline in the exhaust heat is lost completely incinerated under conditions to improve boiler burning power, boiler exhaust gas temperature too high can lead to thermal power boiler decline.

Capacity indicates the amount of water that the boiler can hold in its internal tank. In manual fill boilers, a larger capacity will generally mean a longer heat up time sometimes more than an hour in the largest versions. However, a high capacity 40Ltr boiler can dispense around 180 cups of piping hot water in a single fill.Get a Quote
