It is reported that Haidong Qinghai positive response to the central problem of coal-fired boilers environmental supervision feedback rectification work, to speed up the production of green, zero emissions work processes, and improve air pollution control plan before the end of 2020, out of the central regulation of environmental inspectors feedback 10 tons of steam coal-fired boilers and 35 sets of Haidong since 2013, new registrations per hour.

Haidong county (district) government to fulfill the main responsibility for the area out of small coal-fired boilers, in accordance with their respective administrative areas, to develop the county (district) phase out remediation work plan. A thorough inventory of all the region under pressure coal-fired boiler to install and use cases, and register, identify all cases remediation coal-fired boilers since 2013 new registrations do not meet the requirements, filing one by one. It urged all localities to fully consider the urban built-up area, divided ban on burning areas, local conditions, facilities strategy, apply non-urban area Haidong 20 tons of steam per hour, new coal-fired boilers, and establish normal management mechanism. Meanwhile, arrangements for the rectification of funds, and actively apply for provincial, municipal, county departments of special subsidies, to ensure the implementation of coal to gas coal to electricity, coal-fired boiler, new alternative energy and other projects, and with the central environmental inspectors feedback registration illegal small coal-fired boilers problem rectification work combine to promote the problem has been effectively solved.

Thermal efficiency of coal-fired boilers and boiler standard reference card Is there a difference: in the specific types of boiler, the following will explain to, this kind of boiler coal-fired boiler, and its Web site or in the product, so it is very it is necessary to become familiar with and understand, so that, in order to have a comprehensive understanding of the product website, and also to broaden their knowledge and thus, in its study on the road forward. 1. oil-fired boilers and coal-fired boilers that heat the surface of the furnace, Is there a difference? Fuel oil and coal-fired boilers, which are two major types of boiler, the boiler is in this category, but they get hot surface of the furnace, there is a certain difference, is different, so the on this issue, that the answer is yes. In addition to an outer surface heating furnace, there are differences in other aspects. 2. coal-fired boiler, if it is less than 1 ton of steam, then, the thermal efficiency is how much is? Coal-fired boilers, if it is less than 1 ton of steam, then, the thermal efficiency of the boiler, within the range of 73% -79%, and want to obtain specific parameters, reference may be TSGG0002-2010 "energy saving technology Regulatory boiler regulations, "the standard to obtain accurate values. 3. General boiler certificate, if there is gas and coal-fired boilers of points? Coal-fired boilers, which are how many MW? General boiler certificate, there is no gas boilers and coal-fired boilers of points, so at this point, we should have a correct understanding, you can not go wrong. The MW coal-fired boilers, in general, is 0.35-7MW this range.

In the national standard of water quality standard, the water quality index of hot water boiler stipulates that the total hardness of water supply for chemical treatment outside furnace is less than 0.6 mmol / L. In recent years, in order to reduce the operating cost of heating units, some hot water gas-fired diesel and fire tube steam boilers have been overloaded due to the use of class Ⅲ bituminous coal as fuel instead of class Ⅱ bituminous coal designed to replace the designed type Ⅱ bituminous coal. During the maintenance in summer, it is found that the overloading boiler water wall tube fouling problem is more prominent, some boilers even occur tube burst accident. Why is heating hot water boiler overloaded, scale and even burst tube? Because the calorific value of class Ⅲ bituminous coal is higher, the type Ⅲ bituminous coal of the same weight is burned instead of the designed class Ⅱ bituminous coal. Bituminous coal increases the circulation of boiler riser is not absolute equilibrium, the geometric difference of riser and the heat load are different, so there is inevitably the deviation of flow rate between the risers. Due to the overloading operation of the boiler, some riser tubes are easy to overheat boiling because the flow rate is small, and the wall temperature is higher than the designed wall temperature, so that the scale and even the tube burst are easy to occur. How to prevent the boiler from scaling when overloaded? The heating hot water boiler operates under overload because of the scaling after the superheated boiling. Steam is produced in the process of superheated boiling. The water quality requirement of gas steam boiler is less than 0.03 mmol / L, which is much lower than that of hot water boiler. Water quality requirements. Based on the above reasons, the feed water hardness of heating hot water boiler is reduced, and the scaling phenomenon is eliminated by reducing 0.6mmol/L to 0.03mmol/L.

Henan difference fast boiler diesel and fire tube steam boiler steam boiler is a steam boiler with ordinary steam production machinery and equipment, generally used gas, or coal gas as a fuel, there are an electric steam boiler. Henan fast boiler for the inspection of the steam boiler is a steam boiler gas, fuel oil, gas, and it is common conventional steam boiler with the following differences: "steam boiler supervision norms" and the forthcoming introduction in June next year the new pot rules " boiler safety technology to monitor the specifications "are clearly defined steam boiler needs to be regulated by the state. In other words, users looking to buy a steam boiler plant boiler installation and can not be used directly. Before installation To pot seized by the approval and registration required for installation, and the need for inspection on a regular basis, usually one year during the annual inspection. But there are some of the steam boiler does not require registration and annual inspection, the old rules and the new pan pot regulations stipulate a water capacity less than 30L steam boiler is not within the scope of the surveillance. Because the water capacity of 30L water capacity than at home with a water heater are also small, so there is no risk of explosion, we do not need supervision. Henan water capacity fast boiler steam boiler 26L, belongs steam boiler does not require supervision. Steam boiler explosion hazards generated is amazing. In many steam boiler explosion in the boiler room were razed to the ground, the annual explosion of a steam boiler will be the first to cause casualties and significant economic losses. Henan fast boiler steam boiler is to achieve the ultimate, the boiler body through the scientific design, water capacity is very low, only 26L, itself, there is no risk of explosion on security. The thermal efficiency of conventional steam boiler is only 80%, while the party Henan boiler thermal efficiency of fast gas steam boiler can reach more than 93%. Henan plus energy-saving system fast boiler control systems, the actual energy savings up to 30%, running down a year could save hundreds of thousands of operating costs. The Henan fast boiler steam boiler without boiler room, an area itself is small, you can put in the basement or roof, it can also be placed directly next to the device requires the use of steam. Saving the cost of laying pipe network construction costs and the boiler room, a significant reduction in the use of the initial investment.
