Differentiating between different types of boiler manufacturing equipment and some questions: boiler pressure boilers and pressure boilers, which are in production and manufacturing equipment, whether or not the same? Stoker, the thermal efficiency is how much is? Well, why it is suitable for solid fuels, as well as small boilers burning? In addition, four tons of boiler, fuel is natural gas, then its consumption per hour, how much is? These issues are on the boiler, so the following, the class immediately give a specific answer. Atmospheric pressure boilers and boiler 1. The boiler, which in the production and manufacturing equipment, whether or not the same? Boiler pressure boiler, which in the production and manufacturing equipment, primarily for welding, lifting equipment, measuring equipment and four rolling machine, which may be a welding machine welding, but may be AC ​​or DC welding . But pressure on the boiler, the testing equipment but also this one. So, based on this, on this issue, it is not the answer, that is, both the boiler equipment used in manufacturing, it is not the same.

January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.

Prior to 2017, the total removal of Harbin urban built-up area of ​​small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.

According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.

How many stages does the boiler ignite? Boiler ignition, from a professional point of view, is for heating, combustion and transition to normal combustion three stages. The heating is that the material layer is heated to a certain temperature in order to carry on the work of combustion and so on. For all of us, we should know the three stages of boiler ignition, so that the boiler ignition can be carried out smoothly.

Scale step gralt fired steam boiler cleaning equipment outlined the scale is the source of all kinds of hazards cast iron hot water boiler. Therefore, in order to ensure the safety of cast iron hot water boiler, the economy, the importance of timely removal of boiler scale. DESCRIPTION commonly used in boiler cleaning effective three methods: mechanical cleaning methods, pickling and descaling method boiling alkaline cleaning method. Alkaline descaling effect is worse than the boiling descaling pickling effect. However, alkali boiling, loose scale. Thus, for the removal of hard scale may be treated once prior to hydrochloric acid. Alkali cooking method is simple, relatively small side effects. The disadvantage is a long oven cooking time, the amount of multi-drug ineffective. Mechanical descaling method: when there are loose scaling and hot water boiler slag cast iron, cast iron cooling the furnace after the hot water boiler stops, with water boiler water discharge. Using the spatula, the wire brush and the motor milling tube descaling. This method is relatively simple, with a simple iron fouling characteristics of small hot water boiler. However, labor-intensive, poor cleaning, easy to damage the boiler body. Descaling pickling methods: acid cleaning method using hydrochloric acid or nitric major cleaning. Pickling with hydrochloric acid or nitric acid and a corrosion inhibitor + inhibitor composition. This not only can eliminate the acid wash boiler fouling (dirt removing nitrate, adding hydrofluoric acid), and the corrosion of the cast iron hot water boiler is also less. Pickling and descaling with dissolution, stripping and loosening effect.
