oem iron castings hot water boiler

Many customers prior to purchase gas 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;

The method of starting the boiler during boiler startup control drum wall temperature difference of the process to be controlled in a predetermined drum wall temperature difference may take the following measures within 40 ℃: (1) water temperature before ignition can not be too high, not too fast speed, according to rules of execution. (2) water is completed, the bottom may be put into steam heating conditions. (3) strictly control the raising rate, in particular 0 ~ 0.981MPa boosting speed stage should be less than 0.014MPa / min. Rate of temperature rise not greater than 1.5 ~ 2 ℃ / min. (4) should be regularly switching angle oil gun, until the next row when four full cast oil gun, each part as far as possible evenly heated. (5) via the above-described operation can not effectively control the drum, the lower wall temperature, then when the approach or reach 40 ℃ booster should be suspended, and the sewage regularly, in order to enhance the circulating water, and stabilized until the temperature difference is less than 40 ℃ line boost.

Efficiency

Energy conversion takes place in two stages.The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 % on an HHV basis that is the normal range for a well-optimized power plant boiler.

State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the boiler from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback
