Abstract

The invention discloses a method for calculating the generation power and smoke discharge parameters of a gas engine based on complicated conditions. The method is designed mainly aiming at solving the problem that in existing technical configuration, it is difficult to accurately calculate the generation power and smoke discharge parameters of the gas engine under actual running conditions. The method for calculating the generation power and smoke discharge parameters comprises the steps of collecting and measuring related parameters, calculating the heating power of the compression process,calculating the combustion heating power, calculating the heating power of the expansion process and calculating the calculating the generation power and smoke discharge parameters of the gas engine.By means of the method, the generation power and smoke discharge parameters of the gas engine based on the complicated conditions can be accurately calculated, a basis is provided for the configuration scheme of the gas engine in engineering, the heating efficiency of a whole engineering system reaches the maximum accordingly, and finally the purposes of saving energy and reducing consumption areachieved.

Description

technical field [0001] The invention relates to the field of rotating machinery of thermal engineering, in particular to a calculation method for generating power and smoke exhaust parameters of a gas internal combustion engine under complex operating conditions. Background technique [0002] The building-type natural gas distributed energy system is a comprehensive energy utilization system close to the user end. It uses natural gas as fuel, generates electricity through a gas-fired internal combustion engine, and passes its tail gas through energy conversion equipment to produce heat energy utilization forms required by users, such as domestic hot water, heating hot water, or heat energy for cooling; according to "temperature counterpart, The energy utilization principle of cascade utilization makes the comprehensive energy utilization rate of the whole system greater than 70%. The development of building-type natural gas distributed energy is an effective technical appro...
