Xuchang City in the recently released "2018 campaign of air pollution control plan", especially for the governance of the city's boiler was planned.

Xuchang coal-fired boiler governance objectives:

In Xuchang complete basic steam 10 t / h coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, out of a planned urban area 35 steam tons / hour and coal-fired boiler.

Coal-fired boiler subsidy:

(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

(2) the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

(3) complete Chaigai coal-fired boilers for the end of October 2020, the prize money will not give up.

Xuchang boiler out of the way:

Removal, central heating alternative, coal gas, coal to electricity, use geothermal, wind, solar, biomass with a bag filter, to burn not including clean coal, coal-water slurry, anthracite, charcoal blue, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.

Henan run gas boiler Q & A (III) 1. Henan boiler water wall type of gas main, which has several? A: (1) a tubular water-cooled wall light; (2) membrane wall; (3) water-cooled wall inner walls of the helical groove; (4) a pin-type water-cooled wall (also called stab waterwall tubes). Such water wall surface of the light pipe is required over a certain length of the welding bar, and to facilitate the laying of refractory material is fixed. Mainly used a slagging combustor zone, and certain solid slagging cyclone furnace 2 furnace. Henan role bullnose gas boiler are those? A: (1) increasing the length of the horizontal flue. Because the bullnose is extending into the furnace equivalent to an increase of the horizontal flue bullnose length. Thus, it is possible without increasing the depth of the boiler, the arrangement of the superheater heating surface more. (2) improve the heat transfer effect of the platen superheater. The flue gas from the vertical to the platen superheater in the absence of the bullnose, lateral erosion, erosion to the landscape, increased convective heat transfer effect. (3) increase the flue gas in the furnace so that the fullness of the flue gas distribution in the height direction of the combustion chamber tends to be uniform. Increasing the furnace so that an upper water-cooled wall and roof before the superheater heat absorption. 3. How to structure the bottom of the steam heating apparatus, Henan gas boiler? A: The device is placed along the length of the lower header tank steel in the second line, opened on the pipe holes 5mm diameter (number of holes corresponding to the number of the water wall) and connected to the steam pipe introducing foreign when administered with, intake air is controlled by a valve. 4. ? Principle Henan natural gas-fired boiler circulation is like A: Steel furnace in the cold state, full of inner drum water level elevation below the water evaporation system is stationary. When the tube is heated in the boiler rises, part of the water vapor is generated, forming a mixture of a less dense soda. While the heated downcomer outside the furnace. Water denser tube. In this way both the density difference effect arises impetus, soda mixture flows upward in the water wall, after the header, the catheter into the drum, the downcomer from the drum to the flow of water downwardly through the second line added to the water wall tank, so that the continuous circular flow. The formation of a natural cycle. 5. What is the circulation rate in Henan gas boiler? A: The amount of water entering the recycle loop and the riser G ratio D of the amount of steam at the outlet of the riser pipe is called the cycle rate. 6. The main fault Henan natural gas-fired boiler circulation are those? A: The main fault of the natural circulation circulation stagnation, back, soft drinks stratification, down pipe with gas and boiling heat transfer deterioration. 7. Henan gas boiler water circulation back at what happens? What's the harm? A: The water cycle back phenomenon occurred in the riser direct introduction of steam drum water space, as well as its weight when heated weak pressure differential is greater than the common circuit and the tube. When the vapor bubbles back up the tube with water down flow velocity close, the bubble will not be taken away, stagnant or slow moving state of bubbles increases gradually gathered, vapor-lock is formed, this temperature rise or wall alternating wall temperature, or over-temperature resulting in fatigue failure.

What better boiler Textile refers to a fiber or fiber assembly of multi-scale structure processing technology textile enterprises. Development of textile technology brought us the biggest impact is our clothes. Textile technology type variety, the laundry production process is also different. But regardless of dyeing, drying, tabletting, sizing, dyeing, shaping and other processes are inseparable from the support and cooperation of steam. Therefore, most textile enterprises will choose to use single drum steam boiler prices, textile production processes to ensure normal. Steam is a textile dyeing and finishing, drying, tabletting, sizing, dyeing, stereotypes, such processes are inseparable from the support of power, steam boilers produced steam quality plays a direct product quality after drying and dyeing mills impact, taking into account the steam boiler fuel consumption of the textile industry in general is large, and therefore the textile industry in the choice of a steam boiler, should pay attention to see fuel efficiency, boiler efficiency, steam quality and emissions of harmful substances, high fuel efficiency, high efficiency boilers, steam good quality, less harmful emissions of the boiler, not only can improve textile production textile quality, improve production efficiency, but also reduce operating costs boiler to meet environmental requirements, too. The main square quick steam boiler fueled by natural gas, very clean environment; at the same time using a variety of advanced technologies, such as condensing technology, heat transfer technology wings, FGR flue gas recirculation technology, will greatly enhance the operational efficiency of the boiler, up to 107% above, it is the best option for your mill.

What are the advantages of a common hot water boilers and air heat pumps have? 1, if you are the single drum steam boiler prices, hot water heated by steam, the biggest advantage is cost savings for water treatment, thermal efficiency although almost, but it is still the most comprehensive savings. After the required heating bath of water vapor, the steam is condensed to be a relatively low temperature of the water, the water may be reheated directly back to the boiler. 2, if the direct use of hot water boiler, bath water directly from the hot water supply, will greatly increase the cost of water treatment - Without treatment, after long-term use, hot water boiler heating surface is bound to be a lot of fouling, affecting heat transfer and thermal efficiency. 3, air source heat pumps is the use of a compressor to heat the working fluid, if large quantities of water, it also faces the problem of water treatment. Taken together, if large quantities of water, or the first way is best.
