Function introduction 01 Unit features The natural gas generator set is suitable for operation in a range of multiple environmental conditions, and its economic performance is better than that of the existing diesel engine; The unit can quickly respond to load changes and deal with more complex conditions. The gas generator unit (standby generator for natural gas) adopts the integrated partition box design, the box can meet the operation of multiple environmental conditions, and has the functions of rain proof, sand dust proof, mosquito proof, noise reduction, etc. The box body is designed and produced with special structure and materials of high strength container. l The shape of gas generator box meets the national transportation standard. 02 Unit composition and partition Power generation efficiency (take 250KW as an example for the following data) • The full load gas consumption of the generator set is 70-80nm ³/ h • The power of generating set is 250kw/h • 1kW/h=3.6MJ • 1Nm³/H natural gas calorific value 36MJ • 31.25% ≤ Power generation efficiency ≤ 35.71% • 1Nm ³ The natural gas power generation is 3.1-3.5kw/h Adaptability of gas medium • Applicable gas source calorific value range: 20MJ/Nm³-45MJ/Nm³ • Applicable gas source pressure range: low pressure (3-15kpa), medium pressure (200-450kpa), high pressure (450-700kpa); • Suitable gas source temperature range: -30 ℃ to 50 ℃; • Design and calibrate the optimal system scheme and control strategy according to the customer's gas conditions to obtain the optimal gas source economy and equipment stability.
