Combustion heaters, also known as process heaters or process furnace plants important in many chemical processes and equipment. Combustion heaters provide heat flow to deal with rising temperatures. Obtained by burning fuel burning heaters more than 60\% used in the refinery's energy. Other than refineries, combustion heaters are also used in many chemical process industries, such as ethylene, ammonia, fertilizer-saving, each flame heaters the integration process must be as the cost of energy. The purpose of this study is to develop a system of energy integration in process energy saving flame heaters and optimization of the process of integration is very useful. Positioning tools are useful to optimize and quickly reduce the design options and the potential for large space, with a small number of candidate design deserves more attention. Pinch of fired heaters based on the background processing and analysis technique has been adapted to the present study. Before algorithms as well as graphical technique is proposed to predict flame heaters the integration process of the detailed design of the energy demand. Based on a simplified model of the combustion heater, analytical methods are developed for integrating a flame heater into the overall process. This process helps in estimating the minimum fuel requirements. Minimum and maximum air heater preheating flame temperaturesfor energy efficientintegration also identified. It shows forfiredHeaters using flue gas of hot air preheating only, minimum fuel requirement is an independent air preheat temperature, as long as it is within the minimum and maximum range. Pinch of the following process heat can be used for a further reduction in demand for fuel. In this case, it proves to have a maximum limit for exit to the heat it is clamped in the following procedure can be used. In the course of certain, more total heat of combustion heaters are required to meet utility requirements. A method is proposed for the energy demand required minimum number of combustion heaters. Demand for fuel and air preheating temperature for each flame heater may have to be re-evaluated to set goals. With multiple flame heater, combustion heaters of different responsibilities can vary to simplify the design of heat exchanger networks as a whole. Indirect Integration through fiction site Grand composite curve of several plants in the full potential of the company is established. Grand composite curve represents the total utility of the website provided at any temperature between the two after the maximum consolidation
Through an intermediate fluid erent process. Select the intermediate parameters of processes involving combustion heaters indirectly prove the importance of integration. Steam plant as an intermediate fluid effects have been studied to improve integration between. Flame heater design helps in estimating between convection and radiation of the flame heater parts Division of responsibilities. Process for the detailed design of a fired heater is also reported in this paper. Energy efficientfired heater designed for the development and integration process the objectives set forth in the application is through the refinery's crude distillation unit for example.
