CAMC 260KW 325KVA Methanol Wood Alcohol Generator Set DC Output Water Cooling Electric Start

Core components:

1. Methanol fuel supply system:

* Storage tank: Stores liquid methanol.

* Delivery pipeline: Transports methanol from the storage tank to the engine.

* Fuel pump: Provides delivery pressure.

* Fuel filter: Filters impurities in methanol.

* Injector/carburetor: Atomizes methanol and delivers it to the engine cylinder (most modern units are electronically controlled for fuel injection).

* **Preheating device:** (Often required) Due to the high latent heat of methanol vaporization and difficulty in cold starting, it is usually necessary to preheat the intake or fuel pipeline.

2. Methanol engine:

* Usually modified or designed based on a spark ignition engine (similar to a gasoline engine) because methanol requires a spark plug to ignite.

* Engine materials need to be **corrosion-resistant** (methanol is corrosive to certain metals and rubber).

* The compression ratio is usually designed to be **higher** than a gasoline engine (methanol has a high octane number and good anti-knock performance) to improve thermal efficiency.

* The air-fuel ratio and ignition timing need to be adjusted to adapt to the combustion characteristics of methanol (such as fast flame propagation speed).

3. Generator: coaxially connected to the engine, converting mechanical energy into electrical energy (AC). The type can be a synchronous generator or an asynchronous generator.

4. Control system:
* Monitor engine operating parameters (velocidad, temperature, Presión de aceite, etc.).
* Control injection quantity, ignition timing, preheating device, etc.. to ensure stable and efficient operation.
* Provide protection functions (overspeed, high temperature, low oil pressure, etc.. shutdown protection).
* Manage power output (voltage and frequency stability).

5. Cooling system: cool the engine to prevent overheating.
6. Exhaust system: discharge exhaust gas after combustion.

** Characteristics of methanol as a fuel (affecting unit design and use):

* Liquid fuel: easy to store and transport (compared with natural gas).
* Oxygen-containing fuel: relatively complete combustion, particulate matter and sulfur oxides in emissions are usually low.
* High octane number: allows for high compression ratios, increasing efficiency potential.
* High latent heat of vaporization: causes difficulty in cold starting, requiring preheating assistance.
* Low calorific value (low energy density): methanol consumption is much larger than diesel or gasoline (about 2 times that of gasoline and 2.5 times that of diesel) at the same power output, which means that larger tanks or more frequent refueling are required.
* Corrosiveness: It is corrosive to certain metals (such as aluminum, magnesium, zinc) and rubber and plastics, and compatible materials must be used.
* Toxicity: Methanol is toxic, and safety regulations must be strictly followed during operation and storage.
* Renewability: Methanol can be produced from biomass (biomethanol) or from renewable energy combined with CO2 capture (e-methanol/e-methanol), with a potential carbon-neutral path.
