How module boiler blowdown 1) opening the valve inside the sewage; (2) open the valve slowly outward discharge of sewage to be warmed and sewage pipes; (3) on and off several times from the outer sewage valve, slowly red wash liquid in the boiler fouling, so that the liquid discharge best dirt; (4) turn off the valve inside the sewage, between these two discharge of sewage water in the valve drained; (5) turn off the valve outside the sewage, the sewage termination.

Industrial Fire Tube Steam Boiler Working Principle

The main constructional features of industrial fire tube boiler are one big size steam drum which lies horizontally upon supporting structures. There are numbers of fire tubes come from furnace and also aligned horizontally inside the drum. When the drum is filled with water these tubes are submerged in water.

In mid-June, Yingtan City, Jiangxi Province issued a "Yingtan City People's Government Office on the issuance of three-year action plan to win Yingtan City Blue Sky Battle (2018-2020 years)", Yingtan City Market Supervisory Authority proposed by file stringent targets execution, to carry out a three-year coal-fired boiler special work within the city.

The special rectification, on the basis of thorough investigations within the jurisdiction of coal-fired boilers, the high standard, high-efficiency coal-fired boilers to complete the rectification work to ensure that by the end of 2018 as required successfully completed. 10 out of 21 local stations steam tons / hour and coal-fired boilers and started to build the city and out of the city of 35 tons of steam coal-fired boilers of work; involving the transformation of coal-fired boilers, technical testing organizations should strictly follow the relevant safety technical specifications strict technical clearance, and the overdue completion of the rectification of the enterprise be severely punished according to relevant laws and regulations. Coal-fired boilers by special campaigns, effectively reduce pollutant emissions, improve air quality, help Yingtan beautiful building.

Up to now, the council investigation of coal-fired boiler unit 16, a total of 21 Mopai boiler units, 12 units have been removed, and the rest are in the boiler rectification. Next, the council will further strengthen the regulation of coal-fired boiler follow-up supervision, to ensure that regulation effect.

Let's take a look at the corrosion of the boiler. Do not control the supply of water, the system of hot water for baths, laundry, etc., a 2.8MW dzl series hot water boiler, daily replenishment of nearly 100 tons. The "Water quality Standard for low-pressure boilers" is not carried out conscientiously, and it is clearly stipulated in the standard that when the water supply temperature is ≤ 95 ℃, the PH value of circulating water should be controlled to 10-12, which is a very important indicator, but some units do not implement it. Mistakenly supply hot water boilers according to steam boiler water standards. Heating network pipeline installation is not qualified, circulating water can not be delivered to the end of the system users. If you increase the number of times of air discharge, the drainage will be hot, the drainage will be cool, and the result will be increased Big leaks.
