Optimization of the Calculation of the Thermal Scheme of a Boiler House With Hot Water Boilers

The object of the study is the thermal sources of heat supply systems – one of the most important life support systems. The types of heat supply systems are considered depending on the degree of centralization and the source of heat supply. Their advantages and disadvantages are indicated. The expediency of using a particular heat supply system is determined by a number of conditions. At the same time, each of the heat supply systems is relevant. It is noted that from the point of view of using some types of renewable energy sources as fuel, the most preferred systems are decentralized and centralized with a heat source in the boiler house. When designing new and reconstructing existing boiler houses, an important element of the project is the preparation and calculation of the thermal scheme. During the calculation of the boiler house thermal scheme, when determining the flow rates and parameters of the heat carriers used in the process of preparing water to compensate for losses in the heat supply system, it is necessary to use the method of successive approximations. This complicates the calculation and requires more time for its implementation. A formula is presented to avoid using the method of successive approximations during the calculation of the boiler house thermal scheme. The features of the algorithm for calculating the thermal scheme using the proposed formula are indicated.
