2019 Top Ten High Efficiency Steam Boiler

Many customers prior to purchase gas 2019 top ten high efficiency steam boiler, does not know how to express some of the basic parameters of the boiler, each alphanumeric represents what it means. Today small Henan fast boiler would we explain the argument about 1 tons of gas boiler steam: 1, evaporation: long-term continuous operation of the boiler in the premise of ensuring safety, the number of generated steam per hour, called boiler evaporation, may also be referred to as "output" or "capacity", commonly used unit is "t / h" (t / h). Rated evaporation, refers boiler fuel species design, and operation at the design parameters, i.e. at a predetermined quality of steam (pressure, temperature) and a certain thermal efficiency, long-term continuous operation, the amount of steam produced per hour . The new boiler at the factory, the amount of evaporation on the nameplate marked, refers to the rated boiler evaporation of this. 2, pressure: uniform vertical force acting on the object surface, called the pressure, in units of "Newton (N)", is represented by the last kgf (kgf). 1 kg = 9.81 Newtons force. Vertical uniformly acting on the pressure per unit area of ​​the object, called the pressure, in units of megapascals (MPa). On the habits, often referred to as the pressure of the pressure, so the pressure mentioned in this book, in fact, should be pressure. Design pressure in the boiler, based on the geometry of the pressure member and the strength of the metal material used and the mechanical characteristics and other conditions, is calculated according to the relevant national standards promulgated by the strength of the individual pressure elements are calculated respectively, and then selects one from It can withstand the pressure of the lowest value, as this boiler maximum allowable working pressure. Boiler design working pressure but also said that "Rated outlet steam pressure." 3, steam temperature: indicates the degree of cold objects referred to as "temperature", the internal temperature of the object has a reflection mode energy, the higher the temperature, the greater the energy. Stated boiler steam temperature of the metal plate, that is marked in degrees Celsius. For small boilers, mostly use steam from the upper portion of the main steam valve drum directly drawn, the steam temperature, refers to a saturated steam temperature at the boiler operating pressure air consumption: 1 ton gas steam boiler gas consumption calculated as follows: 1, the thermal efficiency of the boiler 95%; 2, a fuel heating value is 8600Kcal / m³; 3, total output of the boiler was 600,000 Kcal; 4, air consumption of the boiler = 600,000 Kcal ÷ 8600Kcal / m³ ÷ 95% = 73.44 m³;

In recent years, the increasing popularity of Yichun City, Jiangxi Province comprehensive energy saving coal-fired boiler upgrade project, plans to eliminate 75% of the downtown 10 steam tons / hour and below the coal-fired boilers, a ban on new 20 tons of steam / hour and less fuel coal boilers; the rest of principle, then the new 10 steam tons / hour of coal-fired boilers.

Following this, Jiangxi Province Department of Finance issued a special subsidy fund boilers, Yichun downtown 2015--2016 phase-out 10 steam tons / hour coal-fired boilers companies grant. The subsidy standard is: 2 out of steam tons / hour and coal-fired boilers, subsidies to 10,000 yuan / Taiwan; out of steam 2-10 t / h coal-fired boiler, subsidies for 20,000 yuan / Taiwan.

Large and medium-sized boilers in the power and heat industries have high economic losses due to high operating parameters, and the original boilers are smashed. The social impact is huge. Therefore, the water quality of boiler feed water is particularly high (water quality required for power plant boilers, resistivity) >5 MΩ.CM, SiO2 <20 μg/L). In general power plants and thermal centers, water plants are set up to treat boiler feed water.

Ideal Gas boiler system should not substantially leak tight, there is a fixed amount of process water circulating in a cycle to perform endothermic heat within the system.
