calculate suitable waste heat recovery boiler

Need to select the appropriate power, the power when electric calculate suitable waste heat recovery boilers for heating according to heating demand is too large will waste money, power smaller reach to user requirements. In general, electric boilers for heating outlet temperature is above 70 ℃, 30 minutes each household radiator temperature can reach 75 ℃; one cubic meter of heating area needs about 35W of heat, you can combine their own after heating the area to be calculated using the specific electric power boiler.

Chemical plant calculate suitable waste heat recovery boiler belong to special equipment it? Chemical plant boiler belong to special equipment it? For boiler chemical products used will depend on the boiler is not just under pressure to run, there is equipment within the scope of transportation fuels is also in the review of the. There are two boilers are not monitored within the scope of the subject, namely: boiler pressure, the boiler is natural that the pressure and the heating or hot water directly connected users, open system. Household wall-mounted boilers. Chemical plant boiler belong to special equipment it? Special equipment safety supervision regulations in line with the inside of the container is a special equipment and pipes. (2) the pressure vessel is a gas or liquid seal means and the sealing device with a certain pressure. Range pressure vessel is defined as greater than or equal to 0.1MPa (surface pressure) of maximum working pressure, the product of pressure and volume is greater than or equal to 2.5MPa gas, liquefied gas and the maximum operating temperature greater than or equal to TH. Normal boiling point. The fixed and movable with the liquid container; a rated working pressure equal to or greater than 0.2MPa (surface pressure) of the cylinder and a normal boiling point equal to or below 60 degrees Celsius, gas, liquefied gas and a liquid; oxygen chamber and the like. (3) refers to the use of a certain pressure tube tubular device delivery pressure gas or liquid, which is defined as the maximum operating pressure range is greater than or equal to 0.1MPa (specification pressure), the maximum operating temperature greater than or equal to the normal boiling point, greater than a nominal diameter of 25 mm pipes gas, liquefied gas, or steam medium flammable, explosive, toxic, corrosive media.

Recently, Tianjin issued a notice to expand the scope of the ban on high-pollution fuel combustion zone, which is based on high-pollution fuel combustion zone ban on the delineation of Tianjin in 2015, to further expand this range, Tianjin has completed the bulk of urban and rural coal clean energy alternative areas have been completed and no did not go to the construction of Wuqing classified as high-pollution fuel combustion zone ban, and to delineate new range of units street town combustion zone ban.

1, the implementation of zoning classification control. Still requires strict control within the range 2015 designated combustion zone ban, prohibited the use of a single steam of less than 35 t / h of coal-fired boiler, steam 35 tons / hr or higher requires a particularly coal-fired boiler for emission limits or ultra-low emission requirements, while a total ban on all kinds of loose coal burning.

2, ban on burning area has expanded. New ban on burning area of ​​3107.99 square kilometers, Binhai New Area and design Dongli, Xiqing, Jinnan, Beichen, Wuqing, Baodi, Ninghe 9 district and Haihe Education Park. After the adjustment, the city's high-pollution fuel combustion zone ban area of ​​830.54 square kilometers by 2015 increased to 3938.53 square kilometers, accounting for 33.05 percent of the city's total area.

3, clearly biomass fuel control requirements. According to local emission standards biomass fired boiler air pollutants Tianjin promulgated in 2018, re-notice provisions of the central city, Binhai New Area, the seat of government of other towns and other key areas of government regulations prohibit burning biomass briquettes .

What issues need attention when heating calculate suitable waste heat recovery boiler cleaning? Heating boiler and life quality not only has an important relationship, in fact, more important is the usual maintenance, such as maintenance and cleaning is a very important factor to enhance heating boiler life, how to clean has a very important influence on the heating boiler. We buy them from the market to remove scale, rust items mainly by food acid, synergist, metal protective agent composition. Has a strong penetration of scale industrial and residential boilers, steam boilers, heating boilers, etc., rust and sediment, and dissolved peel effect, washed bright as new, non-toxic, harmless and safe to use. Features: First, strong: stripping and dissolve quickly scale, rust, bacteria and algae and other deposits, and turn it into a water-soluble or suspension readily discharged. Second, security: no conventional pickling bring the smoke, hydrogen embrittlement, highly corrosive and burning and irritation on the human body. Product features: fast dissolving calcium carbonate, magnesium carbonate, calcium sulfate, calcium silicate, and iron oxide scale and other ingredients; metal corrosion, non-toxic, rapid and complete removal of scale adhering to the inner walls of the boiler. Usage: one, the detergents diluted with water in 1:10 injection boiler inlet; Second, the top up the water to the highest level, waiting for 4 hours, the reaction scale and full scale remover solution; third, open waste outlet, drain cleaning fluid; IV injection to clear water rinse, cleaning cleaning work is completed. How to clean the heating boiler has a very important impact on our boiler when cleaning the boiler note that the above considerations, we can well enhance the service life of the boiler
