Problems solved by technology

When using spare fuel, it will inevitably lead to a decrease in thermal efficiency and an increase in emissions. If it is used for a long time, it will cause damage to the machine itself
Due to the low calorific value of lean gas, many impurities, and complex components, ordinary micro gas turbines cannot burn lean gas stably

Embodiment Construction

[0016] Mode 1: When the calorific value of the gas or liquid fuel is stable, normal fuel is supplied to the gas or liquid fuel combustor (work flow reference dotted black arrow).

[0017] Mode 2: When the calorific value of the gas fuel is unstable, normal fossil fuel fuel is supplied to the two flame tubes of the combustion chamber, and lean gas is supplied to the remaining six flame tubes. (Workflow reference dotted line black arrow).

[0018] Mode 3: The solid fuel combustor is used when there is a stable source of solid fuel such as wood chips, biowaste, and industrial waste (workflow reference dashed black arrow).

[0019] By replacing the flame cylinder, the efficient combustion of fuels with different calorific values ​​of gas or liquid fuels can be realized. Fuels currently available: diesel, ethanol, fusel oil, liquefied petroleum gas, natural gas, propane, butane, biogas, biomass gas, hydrogen mixture, lean gas with a calorific value below 15MJ / m3. Due to its low c...

Abstract

The invention provides a novel micro gas turbine power generation system. A micro gas turbine can use several kinds of fuel under the conditions that the heat efficiency is not lowered, and emissions are not increased, and lean gas of which the heat value is lower than 15 MJ / m<3> is generally burned as industrial tail gas in vain. The lean gas can be used without adding expensive auxiliary fuel. In addition, under the condition that a core machine is not changed, solid fuel such as wood bits, biological waste and industrial waste can be efficiently combusted through additionally arranging an auxiliary combustion chamber. The micro gas turbine can avoid waste and pollution caused by ineffective combustion of the lean gas or direct emission, to the atmosphere, of the lean gas, and can avoid environment pollution caused by city biological waste and industrial waste.

Description

Technical field [0001] The invention relates to a new type of micro gas turbine power generation system, which can use various fuels, especially gas with low calorific value and solid fuel, and can meet Euro 6 emission standards in terms of environmental protection. Background technique [0002] Micro gas turbine is a kind of small heat engine, which is widely used in distributed power supply, combined heat and power supply, backup power supply, etc. It has the advantages of small size, light weight, simple structure, multiple fuels, low noise, low emission, low vibration, and low maintenance rate. [0003] Although a micro gas turbine can use a variety of fuels, it is based on one fuel and takes other fuels into consideration. When the spare fuel is used, it will inevitably lead to a decrease in thermal efficiency and an increase in emissions. If it is used for a long time, it will cause damage to the machine itself. Due to the low calorific value, many impurities and com...
