How to choose heat fluid boilers?

For the selection of heat fluid boilers, first step is to determine several parameters: thermal power in the process, the oil temperature, and the use of waste heat.There are several methods for determining the boiler's thermal power:1. Calculation. According to the specific heat capacity of the material to be heated, the heating temperature difference, the processing amount per unit time, etc., the thermal power is equal to the product of the above three points, and the calculation result considers a certain margin amount as the boiler capacity.2. The sum of thermal power in the process equipment can also be used as the basis for the heat power.3. Refer to the experience of the same industry to increase or decrease on the basis of peers.4. If steam heating is used, it can be converted into heat transfer oil of the same tonnage and the capacity is appropriately reduced.The determination of the temperature of the heat transfer oil can be determined according to the characteristics of the heated material, and the heat transfer temperature difference is appropriately considered. The inlet and outlet oil temperature is generally determined by 20-30 degrees.The temperature of the exhaust gas of the heat fluid boiler is generally high, and the waste heat has various utilization schemes, which can be used to generate low pressure steam, or hot air, or to preheat the air.When the thermal power, heat temperature and waste heat utilization scheme of the heat transfer oil boiler are determined, the general heat transfer oil manufacturer will give you a detailed system solution. Comparing the quality of a system plan is mainly to see the overall efficiency of the system.
