In industrial combustion and automotive thermal management, the ignition system plays the role of the "first spark." Whether it is the safe start-up of a natural gas boiler or the reliable operation of a parking heater on a cold winter night, both rely on a key component – the High Voltage Ignition Transformer. It converts low-voltage power into high-voltage pulses of tens of thousands of volts, generating a spark between the burner electrodes strong enough to ignite the fuel. If ignition fails, it can mean production stoppage, heating interruption, and even safety hazards.
Scenario 1: The Core of Industrial Combustion – Boilers and Kilns
Challenges:
- Boilers and kilns require long-term continuous operation in high-temperature, dusty, and high-vibration environments
- Ignition failure can cause fuel accumulation, creating a risk of deflagration
- Electrodes are exposed to flames for extended periods, requiring ≥8kV high voltage to reliably break down the ignition gap
HT Series: Metal Housing Solution
- Metal housing provides high mechanical strength and good heat dissipation, suitable for harsh operating conditions
- HTS-8B: ≥8kV output, ≥20mA, single-pole output, suitable for natural gas burners
- HTS-10A: Dual-pole output (2×5kV), 6mm ignition gap, suitable for heavy oil / mixed fuels
Scenario 2: Commercial and Domestic Gas Appliances – Compact and Reliable HTS Series
Challenges:
- Limited internal space in commercial kitchens (gas stoves, fryers, ovens) and wall-mounted boilers
- Need for good insulation performance and long service life
- High safety requirements due to direct user operation
- Must provide sufficient high-voltage output within a compact package while meeting flame-retardant and insulation standards
HTS Series: Plastic Housing Solution
- Plastic housing, lightweight with excellent insulation performance, specifically designed for small burners and gas appliances
- HTS-7: 1×7kV single-pole or 2×4kV dual-pole output, ≥15mA, ignition gap 3-4mm, suitable for small gas appliances
- HTS-8B: ≥8kV single-pole output, ≥20mA, ignition gap 3-5mm, suitable for higher-power commercial gas stoves
Scenario 3: Mobile and Vehicle Applications – 12V/24V Electronic Ignition Transformer
Challenges:
- Parking heaters, vehicle fuel heaters, and similar devices do not have access to mains power (220V AC)
- Must rely on vehicle battery power (12V or 24V DC)
- Need to meet requirements for small size, light weight, and resistance to vibration and shock
- Must start reliably in low-temperature environments
Electronic Type: Low-Voltage DC Input Solution
- Supports 12V DC or 24V DC input, powered directly by the vehicle battery without the need for an inverter
- Epoxy resin encapsulated structure, compact with strong vibration resistance, suitable for direct PCB mounting
- Output voltage range: 4kV to 7kV, suitable for parking heaters, diesel air heaters, and similar equipment
- Operating temperature range: -30°C to +70°C, with reliable low-temperature performance
Core Technology: Precise Matching of Single-Pole and Dual-Pole Output
The output method of a high-voltage ignition transformer is not one-size-fits-all. It must be matched to the fuel type and burner structure. SHINHOM offers two output modes:
| Output Type | Working Principle | Suitable Fuel | Typical Applications |
|---|---|---|---|
| Single-Pole Output | One high-voltage electrode discharges to ground (burner metal wall) to create a spark | Gas (natural gas, LPG) | Gas boilers, domestic gas stoves, wall-mounted boilers |
| Dual-Pole Output | Two high-voltage electrodes discharge directly between each other to create a spark | Fuel oil (diesel, heavy oil) | Oil-fired boilers, industrial burners, heaters |
Gas burners typically use single-pole output, where the high-voltage electrode discharges to ground with a simple structure. Oil burners use dual-pole output, generating a spark directly between the two electrodes without relying on a ground return circuit.
Summary: Selecting the Right High-Voltage Ignition Transformer for Your Application
The selection of a high-voltage ignition transformer requires consideration from four dimensions: fuel type, power supply conditions, installation space, and operating mode.
| Application Scenario | Recommended Product | Key Features |
|---|---|---|
| Industrial gas boiler | HT Series (Metal Housing) | ≥8kV output, continuous operation, high mechanical strength |
| Industrial oil-fired kiln | HTS-10A (Dual-Pole Output) | 2×5kV output, 6mm ignition gap |
| Commercial gas stove | HTS-7 or HTS-8B | 7-8kV output, compact size |
| Parking heater | Electronic Type (12V/24V DC Input) | Low-voltage DC input, vibration-resistant potting structure |
| Domestic wall-mounted boiler | HTS-7 (Plastic Housing) | Lightweight, good insulation, intermittent operation |
The SHINHOM high-voltage ignition transformer series supports customised solutions. Output voltage, input voltage, housing material, and mounting method can all be adjusted based on specific application requirements.
