packaged double drum steam boiler

Recently, the Tianjin Municipal Government issued the latest "2018 ~ 2019 autumn and winter tackling air pollution comprehensive management action plan" (the "Program"), "plan" put forward specific remediation requirements: the city's 65 steam tons / hour and above the basic realization of coal-fired boilers coal-fired power plant ultra-low emission standards, the development of energy-saving and ultra-low emissions rehabilitation programs for 65 steam tons / hour or more coal-fired boilers, the implementation started after the end of the heating season. Before the end of this year, within the city basically eliminated 35 tons of steam / h and coal-fired boilers of 25 iron and steel industrial enterprises discharge waste depths of governance, the basic completion of the iron and steel, building materials, thermal power, coking, casting and other key industries and coal-fired boiler fugitive emissions control.

"Plan" the implementation process to uphold the objectives warm winter and clean heating double standards, combined with the actual development of coal-fired boiler rehabilitation programs, to ensure completion before the end of the year 206,100 rural residents to use clean energy alternative to coal for combustion. Guidelines established after the first break, for the substitution of gas for coal to electricity instead of coal and other alternatives, in the case of gas supply, power supply is not implemented, the existing heating facilities will not be dismantled until the gas supply, power supply after the successful implementation be removed. And to develop high-pollution fuel combustion zone ban zoning adjustment programs, complete with electricity instead of coal, substitution of gas for coal in the region included the range of high-pollution fuel combustion zone ban. For failure to implement the heating area clean, good smokeless coal tender, production, supply, to ensure smokeless coal substitute the existing polluting large coal-fired boilers. Among them, before the heating period to complete large-scale centralized distribution, heating Doing the fragmented coal blending, before the end of December 2018, the actual realization of bulk coal dealers cleared.

Many customers prior to purchase gas packaged double drum 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;

When choosing a gas boiler manufacturers of what should be the standard? Want to make good quality gas boiler, first you need to select a good manufacturer, only one manufacturer has enough advantages, will make the product quality is guaranteed. When Hui user selection of such manufacturers, naturally, need to have their own standards, so when this choice of manufacturers, should be on what standard? First you need to see what kind of scale of the manufacturers standards. Among the industries, there will be a big difference in scale between the manufacturers and the manufacturers, manufacturers may be able to carry out small-scale production, but in no way on the strength of large manufacturers and compared.

When the boiler operation, the reason of maintaining the water level in the normal range: the boiler drum water level is too high, will affect the effect of water separation, the wet saturated steam fraction increases, increased salinity, and likely to cause wall superheater Steam Turbine sCALING stream, superheater flow area decreases, the resistance increases, to improve the heat resistance, the wall-temperature, and even burst pipes; the other also result in increased moisture vapor turbine efficiency is lowered, increasing the axial thrust and the like. Serious water superheated steam temperature over a sharp decline in the steam piping and steam turbine to generate water impact. Cause devastating accidents.
