Features of Using the Regulatory Method "Thermal Calculation of Boiler Units" for Firetube Boilers
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2018, Vol 27, Issue
Abstract
In recent years, the practice of using fire-tube and fire-fighting water-heating boilers in the replacement of service water heating boilers in boiler-houses has become commonplace in the district heating systems of the cities of Ukraine. In this case, fire-extinguishing boilers can be used both imported and domestic. Designing boiler houses with such boilers and especially their construction often requires a heat calculation boiler, either test or constructive, but there is a problem. The normative document "Heat Calculation of Boiler Units" operating in Ukraine does not contain any instructions on calculation of fire-tube and boiler boilers. He gives orders for the calculation of water heaters and steam boilers, in addition, only with a capacity of more than 75 t / h. These guidelines can not always be used directly, directly. For example, for fire-tube and fire-fired boilers, heat pipes with a wavy wall surface are used. Such a case is not provided in the Normative document. There are difficulties in determining the parameter M which takes into account the nature of the temperature distribution along the height of the flue pipe and depends on the relative location of the maximum flame temperature and some others. The presence of such problems necessitates the development of a special regulatory document with recommendations for the heat calculation of fire-fueled boiler boilers or an annex to the current normative document devoted to solving this problem. A description of the main problems that arise during the heat calculation of fire-tube and boiler boilers with the help of the normative document "Heat calculation of boiler units" in Ukraine is presented and the way of their solution is shown
