advanced water tube boiler

Many customers prior to purchase gas steam advanced water tube 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;

Testing of welded joints of gas-steam oven steam oven gas requirements of welded joints testing requirements are listening to the views of the relevant units, based on the provisions of the relevant specifications and reference made. This procedure is not a gas phase and a liquid phase furnace furnace testing requirements are proposed, but to present different requirements depending on the pressure element. 1. A vertical gas steam drum furnace girth welds, seam head as a radiation or ultrasonic waves of at least 25% ray detection, substantially existing steam advanced water tube boilers and hot water boilers procedures consistent with the requirements, increased only allows for ultrasonic waves of at least 25 % of prescribed ray detection, and version 80 as steam boiler code requirements. Such ultrasonic waves of a predetermined main consideration 25% ray detection, can detect the presence of defects in the weld, meet safety requirements, and can reduce the production cost. 25% of the longitudinal seam ray detection must include cross-linker and a girth section. 2. For testing butt joint pipe heating surface, where heat is different according to each request. Different heating means by radiant and convective heat. In the draft, and 25% were defined as 10% of random testing. Feedback back in, some units considered low requirements, proposal to change, and 50% is appropriate; some units believe that this requirement can also be lower. After analysis, we adopted an opinion, not less than 10% of the radiant section ray detection checks; convection section of not less than 5% radiographic inspection checks. The main consideration butt weld heating surface prescribes the use of gas welding, quality can be guaranteed. The present specification further calculation and sampling rate testing method makes provision to make this procedure more operational. 3. In addition to gas steam boiler drum furnace gas should be mechanical tests, the furnace drum and all the liquid organic heat carrier furnace heating surface tube, pipe butt joints are not required mechanical tests. Therefore, the present production procedure drum furnace gas only make a check each of ten test panels. Other cases are not required to do testing test panels. The main consideration is relatively low liquid pressure furnace, while the present specification welding method does not only clearly defined, but also for the welding procedure requests, can guarantee the quality and properties of the weld.

The difference between hot water advanced water tube boiler and steam boiler:? Depending on the media outlet, we will easily be divided into two hot water boilers and boiler steam boiler. But many people still do not know how they are used. Simply put, hot water boiler is used for heating, hot water, such as bathing, swimming pool, community and other places are required, even it is said that, as long as the place is in need of heating, hot water boiler needs now Zheng pot design and production of hot water boiler is the largest tonnage of 160 tons (116mw) circulating fluidized bed hot water boiler; and steam boilers are mainly used in chemical, building materials, textile and other industries for the production of steam supply, of course, it can also be heating, but are generally manufacturing plants, industrial parks heating way, is a case of cogeneration.

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired advanced water tube boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
