High Quality Coal Gasification/Coal Gasifier Design for Indonesia Coal or Other Coal
30% Energy Saving Coal Gasifier Generator
This model of coal gasifier is a new intelligent, high-efficiency, and environmentally friendly product developed by our company. It features a patented slag-removing rotating ash pan and an automatic slag removal system, which significantly improves the efficiency and reliability of the equipment.
The gasifier uses a special pagoda-shaped heat-resistant iron grate, ensuring that the furnace walls are always protected by slags. This design enhances slag breaking, loosening, and ventilation, effectively reducing maintenance and improving performance. It also breaks away from the traditional concept of coal gasifiers being similar to pressure vessels, with a built-in automatic temperature control system for better operation.
**Working Principle:**
The coal gasifier utilizes 10–50mm pea coal as an ideal fuel, which greatly increases the gasification intensity, accelerates the reaction, and improves the gasification rate of coal. The charcoal reacts with steam to produce combustible gases such as carbon monoxide and hydrogen, achieving complete and continuous gasification.
**Environmental Benefits:**
Tested by the Henan Environmental Testing Center, this coal gasifier produces no smoke during combustion. The emissions of both sulfur dioxide and soot comply with the GB9078-1996 environmental standards, making it a clean and eco-friendly solution.
**Safety and Reliability:**
Equipped with national invention patent technology, this gasifier eliminates the risk of explosions commonly associated with traditional models, ensuring safe and stable operation.

This energy-efficient coal gasifier is ideal for industrial applications where clean and reliable fuel gas is required. It offers excellent performance, low emissions, and long-term durability, making it a smart choice for modern energy systems.
The role of the valve is specifically responsible for the input of air into the engine and exhaust the exhaust gas after combustion. From the engine structure, it is divided into intake valve and Exhaust Valve.
The role of the intake valve is to draw air into the engine and mix it with the fuel to burn; The function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat.
The valve is composed of a valve head and a rod. The valve head temperature is very high (intake valve 570~670K, exhaust valve 1050~1200K), but also withstand the pressure of the gas, the valve spring force and the transmission component inertia force, its lubrication, cooling conditions are poor, requiring the valve must have a certain strength, stiffness, heat and wear resistance.
The intake valve is generally made of alloy steel (chromium steel, nickel-chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chromium steel).
Sometimes in order to save heat resistant alloy, the exhaust valve head is made of heat resistant alloy, and the rod is made of chromium steel, and then the two are welded together.
