SCZ 10.0T Economic Diesel Engine Fuel Expander

1.Introduction：

The boiler hydrogen - assisted combustion apparatus developed by Shichun is an energy - efficient and high - performance device specifically designed for composite combustion in chain grate boilers. It is the leading application configuration system in China, seamlessly integrating two different combustion methods: localized coal combustion and hydrogen combustion in chain boilers.

The hydrogen generator is at the core of the boiler's hydrogen combustion system. It employs high - voltage inverter DC pulse technology, which effectively overcomes the technical challenges of low efficiency and high power consumption typically found in traditional water electrolysis for hydrogen production.

2.Components ：

Hydrogen Supply

High - pressure hydrogen is first stored in a dedicated storage unit, such as a hydrogen cylinder or a storage tank. Then, it is depressurized via a pressure - regulating valve to the specified working pressure range of 0.1 - 0.5 MPa. Before being supplied to the burner, the flow rate of the hydrogen is carefully controlled by a flowmeter.

Fuel Mixing & Combustion

In the burner, hydrogen is mixed with combustion air or oxygen, producing a high - temperature flame (reaching up to 2,000°C). Upon ignition, the mixture efficiently heats the boiler's heating surface. Moreover, the clean combustion of hydrogen (with water vapor as the by - product) dilutes pollutants like NOₓ and CO₂ emitted from the primary fuel.

Intelligent Control System

This system monitors real - time parameters such as temperature, pressure, flow rate, and O₂/CO levels. It dynamically adjusts the air - fuel ratio to optimize combustion efficiency and ensure safety. Safety interlocks, including anti - backfire valves and leak detection devices, are incorporated to prevent potential hazards such as hydrogen leakage or flame backflow.

3.Application：

Industrial Scenarios

Applied in chemical, metallurgical, food, papermaking, and other industries, it meets the requirements for high-temperature heating and environmental protection. Examples include heating chemical reactors and metal rolling furnaces to enhance efficiency and reduce emissions.

Commercial and Residential Settings

In commercial and residential contexts (e.g., central heating systems, hotels, data centers), it facilitates low-carbon transition-for example, upgrading traditional boiler heating and providing stable heat sources to data centers.

Special Scenarios

Special applications include hydrogen-powered ships, coal-fired power plants undergoing hydrogen co-firing, and aviation deicing, addressing the needs for mobile heating and transitional technologies.

Hydrogen Supply: Produced via electrolysis or external storage, hydrogen is depressurized to 0.1–0.5 MPa and flow-controlled to the burner.

Mixed Combustion: Mixed with air/oxygen at a 34:1 air-fuel ratio, it ignites to form a 2,200–2,800°C flame, heating boiler surfaces.

Intelligent Control: Sensors monitor parameters (temp, pressure, flow), with a PLC adjusting the air-fuel ratio for 95%+ efficiency. Safety features include flame arrestors and leak detection.
Key benefits: Zero carbon emissions, 5–15% higher efficiency than traditional boilers, and suitability for industrial/commercial heating.

6.Q&A:

Q1: What Is a Boiler Hydrogen Combustion - Supporting Machine?

A:
It is a high - efficiency combustion device that uses hydrogen as fuel or for combustion support. Hydrogen is generated through water electrolysis or supplied externally. It is then mixed with air/oxygen and produces high - temperature heat for boilers. Key advantages include zero carbon emissions, a thermal efficiency 5%–15% higher than that of traditional boilers, and suitability for both industrial heating and central heating systems.

Q2: How Does It Work?

A:

Hydrogen Supply: Hydrogen is supplied either via water electrolysis or from storage tanks. It is depressurized to 0.1–0.5 MPa and its flow is controlled by a flow meter before reaching the burner.

Mixed Combustion: Hydrogen mixes with air/oxygen at an optimal air - fuel ratio (e.g., 34:1 by mass) and ignites to form a high - temperature flame (up to 2,800°C in pure oxygen) to heat the boiler.

Intelligent Control: Sensors monitor parameters such as temperature, pressure, and flow rate in real - time, adjusting the air - fuel ratio to maximize combustion efficiency.

Q3: What Is the Future Development Trend?

A:

Green Hydrogen Adoption: As the costs of solar/wind - powered electrolysis decline (projected to be ≤$2/kg by 2030), there will be widespread use of green hydrogen.

Blended Combustion Transition: Coal - fired power plants will first adopt a 5%–20% hydrogen - blending ratio before fully transitioning to hydrogen - only combustion.

Smart Integration: Integration with the Internet of Things (IoT) will enable remote monitoring, fault prediction, and energy optimization, enhancing the system's reliability.

Q4: Which Industries Are Suitable for Pilot Projects?

A:

High - Energy/Emission Industries: Industries such as steel, chemicals, and paper manufacturing, which need to rapidly reduce carbon emissions to meet compliance requirements.

High - Precision Heat Demand Industries: Semiconductor manufacturing and aerospace ground support, which require clean high - temperature heat.

Policy - Supported Regions: Hydrogen demonstration zones in China, the EU, etc., which benefit from subsidies and infrastructure support.
