effects of freshwater on steam boilers

Porous materials have always been the main sound absorbing material, such as glass wool. The structural feature of porous sound absorbing materials is that there are many small gaps in the material. When sound waves are incident on the surface of the porous material, they can enter the pores, causing vibration of the air and material within the pores. The friction and viscous action of the air converts the kinetic energy (sound energy) of the vibration into heat energy, thereby attenuating the sound waves. The experiment proves that the sound absorbing material has better absorption for medium and high frequency, and the low frequency absorption performance is poor. Fangkuai Boiler uses a sound-absorbing technology combined with a porous material, and uses a sound-absorbing panel and a muffler chimney to effectively reduce the noise generated during boiler operation.

How boilers and furnaces and bath boiler tubes What are the requirements? Boiler and furnace, which is what you need to know? About boiler, which related to difficult problems, not in front, but the urgent need to know and understand? Ask these questions, its main purpose is to be completely resolved, thus, help you to successfully use the boiler, and then, get good use of effects and economic benefits. 1. boiler and furnace, what should it be? Boiler and furnace for a specific process is as follows: first steam valve and opens slowly, not too fast to avoid problems such as instability vapor pressure, then, two boilers are coordinated and slow overload. If in the process, risk factors found to affect the safe operation of the boiler, then it should stop immediately and steam until after the elimination of these negative factors, then steam and work. Also, pay attention to adjust the water level in the steam load is moderate, not any problems. 2.G1, G2, etc., specifically refer to? Central boiler furnace temperature is generally controlled to what extent? G1, which refers to a stoker boilers, G2, refers to two stoker boilers. And so on, G3 refers to three boiler fireman. The reference standard for TSGG6001-2009 "boiler safety management and operational personnel examination outline." As for the center temperature of the boiler furnace, under normal circumstances, it is controlled in this range 900 ℃ -1100 ℃. 3. bathing in the boiler tubes, what requirements? In addition, the auxiliary boiler, which is the general concept of it? Boiler tubes in the bath, is not predetermined portion of its media activities, media emptying can then be emptied as far as possible, can not be emptied, it should regularly discharge or take microfluidic way to avoid frozen pipes this problem occurs. The auxiliary boiler, which is a general concept, therefore, on the issue of two, whose answer is yes. Further, in the upper part and which apparatus comprises means, there are many, here, not one is illustrated.

December 29, 2018, Yulin City, Shaanxi Provincial People's Government issued an iron fist rule on blue haze win the Battle of three-year action plan (2018-2020 years) (hereinafter referred to as the "Program").

That "plan", mainly to adhere to all the people cohabitation, source control, continued implementation of air pollution control operations, improve the city's air quality, determined to win the battle of the blue sky efforts. Details are as follows.

1, the construction of high-pollution fuel combustion zone ban. Deadlines have been designated high-pollution fuel combustion zone ban construction of combustion zone ban prohibits the sale, burning polluting fuels, a ban on new or expanded high-polluting fuel burning facilities have been built in the city and county governments should provide the within switching to natural gas, liquefied petroleum gas, electricity or other clean energy sources.

2, to further promote the bulk coal governance. Promoting rural residents, agricultural production, clean energy alternative to coal-fired commercial activities, take electricity instead of coal, substitution of gas for coal, and biomass, wind and solar and other clean energy alternatives.

3, accelerate the transformation of governance-fired power plants. Accelerate the construction of wind power, photovoltaic and other non-fossil energy electricity generation. Implementation of the provincial special program, shutting down vigorously eliminate environmental protection, energy consumption, security is not up to 300,000 kilowatts coal-fired units. Capacity to shut down the unit, coal consumption and pollutant emission targets to carry out a transaction or replacement.

4, prohibiting new coal-fired central heating station. New heating all use natural gas, electricity, heating Renewable energy (including biomass clean heating, solar heating, heating and other industrial waste heat), to give priority to distributed clean energy central heating, residential buildings do not have the conditions, you can access municipal centralized heating.

5, to carry out comprehensive improvement of coal-fired boilers. The city is no longer a new 35 tons of steam per hour of coal-fired boilers, 65 tons of steam per hour and above all coal-fired boilers and energy-efficient ultra-low emissions to complete the transformation. Increase the small coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment and other efforts to phase out coal-fired facilities, phasing out 10 tons of steam per hour and coal-fired boilers. Low NOx combustion gas boiler to carry out the transformation. Before the end of 2020, the conditions of the conventional gas combustion boiler completed low nitrogen transformation, after transformation of nitrogen oxide emissions is not higher than 80 mg / m. Urban built-up area of ​​ultra-low emission biomass boilers implement reform.

6, strengthen straw Jinshao main responsibility. To carry out special inspections straw Jinshao in the summer harvest and autumn harvest stage. Due to open burning of straw to prevent regional heavy pollution caused by the weather.

7, pin good job of storing system for gas production. Gas supply priority for city residents and substitute coal for heating in winter. "Coal to gas" adhere to the "gas will change" to ensure safe construction, safe use, and safety management. Orderly development of natural gas peaking power plants and other interruptible customers.

8, speed up the upgrading of rural power grids. Urban counties to formulate a work program. Power grid enterprises to co-ordinate the construction of power transmission and transformation project to meet heating demand for electricity residents. Encouraged to promote regenerative and other electric heating. Governments at all levels to "coal to electricity" project supporting grid should be given support, coordination "of coal to electricity," "coal to gas" land for construction.

9, improve energy efficiency. Continue to implement the action of the total energy consumption dual control and strength. Improve energy efficiency standards, develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage. New projects in key areas of high energy consumption per unit of product (output) energy consumption should reach the international advanced level.

10, to accelerate the development of clean energy and new energy. Optimization of wind energy, solar energy development layout. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas.

How electric boiler buried? 1. The electric boiler tube end polishing rust, rust length not less than 50mm. 2. Check acceptance buried electric boiler manufacturing quality standards by drawing check the quantity and quality of buried pipe manufacturing, defective and does not meet the requirements should be repaired, corrected qualified. 3. The electric boiler as buried by the root ball pass the test, what buried? Should not pass the ball flush. 4. Infrastructure for quasi tube fitted.

Water Maintenance Essential to Prevent Boiler Scaling

The inspector should inspect the boiler's piping systems for leakage, because any leakage is unacceptable and should be a cause for concern. All water lost from the system must be replaced by the addition of untreated fresh water. This can create more problems, because fresh water brings a new supply of those scale-causing minerals.
