Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast boiler steam signed a 0.5-ton electric heating 18tons rice husk fired steam boiler in vietnam which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
100,000 square heating using pressure hot water boiler pressure hot water boiler or heating using 100,000 square pressure hot water boiler pressure hot water boiler or heating using 100,000 square pressure hot water boiler or pressure hot water boiler heating needs 100,000 square meters select at least 20 tons of hot water boiler. Boiler pressure does not apply to a boiler larger than 1 ton. Accordingly, the recommended pressure boiler are as follows: 1, high-pressure boilers energy consumption since no pressure boiler, the boiler can not overcome the hydrostatic pressure end of the system, static pressure end of the system can only be overcome by a circulation pump sag. Therefore, the atmosphere should be strictly called boiler circulating pump pressure pump, which should include at least lift force and maximum static pressure of the building, the pump head is much higher than the boiler pressure, boiler pressure much higher than the pump power. 2, the boiler water pressure boiler pressure loss is greater atmospheric pressure fluctuation, the condition is unstable, and loss of water systems. If the boiler is small, it is best supplemented with tap water. If supplementary water softener, operating costs will be much higher. Thus, the general pressure boiler make-up water with tap water. But the quality of tap water, especially in the northern hard water, tap water replenishment sh boiler tube Bouquet scaling is very serious, greatly affect the life of the boiler. 3, corrosive atmospheric pressure boiler boiler is self-contained, its oxygen permeability severe corrosion and oxidation than pressure boilers. Thus, the system piping and equipment must be processed through the boiler atmospheric oxidation. Since China's technology was not mature, widely used products on the market basically is not possible, therefore, oxidation corrosion of pipelines and terminal equipment and the use of scrap speed Boiler pressure much faster. Based on the above three, atmospheric boiler only for small-scale projects, the demand is not high pressure boiler 10 square heating should be selected.
A specific pressure adjustment apparatus is needed in the boiler such as safe valve pressure gage, water indicator to stabilize the gas pressure. Because the instability of the pressure probably lead to combustion instability or lead to temper or blow -of.
The steam pipe of the 18tons rice husk fired steam boiler in vietnam is recommended to use seamless steel pipe because it can have good performance and use effect. Moreover, this is also clearly required in the relevant standards.
