Electric Steam Boiler: Working Principle, Price & Key Advantages

1.Introduction

Electric boilers utilize electric energy to heat water to boiling, thereby producing steam. They are widely used in industry, medical, food processing, and other fields. This article will introduce you to the content of electric steam boilers.

2.What is an electric steam boiler?

Electric boilers are also known as electric heating steam boiler. It consists of electric heating tube, boiler body, control system, steam-water separation unit and other components. According to working pressure, they can be classified into three types, low pressure（≤1.6MPa）, medium pressure（2.5-3.9MPa）, and high pressure（≥9.8MPa）. Among them, low-pressure products are the most widely used in civil and small-scale industry sectors. Unlike gas-fired and oil-fired boilers, electric steam boilers do not require fuel storage devices or complex smoke treatment systems. Their overall structure is more compact and the installation conditions are more flexible. According to structural forms, electric steam boilers can be classified into vertical and horizontal types. Vertical electric steam boilers have a smaller size and suitable for small enterprise users. Horizontal electric steam boilers have a larger size and higher efficiency.

3.The working principle of electric steam boiler

The working principle of an electric steam boiler is to use electricity as an energy source to heat the electric heating elements in the boiler, and transfer the heat energy to the water in the boiler body, so that the water is heated to produce steam. Specifically, electrical energy heats water through resistance wires or solenoid coils, causing it to boil to produce steam. Steam is transported through pipelines to heating equipment for heating or power output. After the steam condenses, the water flows back to the boiler for recycling.

4.The efficiency of electric steam boiler

The efficiency of electric steam boiler is relatively high, its thermal efficiency is reaching above 98%. Compared with gas-fired boiler, oil-fired boiler and other products, electric steam boiler has higher thermal efficiency.

5.The pros and cons of electric steam boiler

Pros

Clean and environmentally friendly: Electric steam boilers use electricity as energy source and do not produce direct emissions during operation, which has a low impact on the environment.

Intelligent operation: Equipped with a microcomputer automatic control system, supporting functions such as water level control, water shortage protection, and overpressure protection.

Low maintenance costs: The structure is relatively simple and the maintenance costs are low.

Easy Installation: Small footprint, no need to set up chimneys and pipes.

Cons

High operating costs: The operating costs of electric steam boilers are relatively high, mainly due to higher electricity prices.

Strong dependence on power supply: Stable power supply is required.

6. How to choose electric steam boiler and gas steam boiler

Environmental performance: The electric steam boiler does not produce direct emissions during operation, and the environmental performance is better. Emissions from gas steam boilers can be further reduced by technical means.

Maintenance costs: Electric steam boilers have a simple structure and low maintenance costs. Gas steam boilers have a complex structure that requires regular maintenance and inspection.

Installation space: The electric steam boiler occupies a small area and is easy to install. Gas steam boilers may require more space to install associated equipment and piping.

Operating Costs: The operating costs of electric steam boilers are relatively high, mainly due to higher electricity prices. Gas steam boilers have relatively low operating costs.

7. How much is an electric steam boiler?

Small civil model (0.1-0.5 tons/hour): The price is 15,000-50,000 yuan, suitable for catering disinfection, small laundry rooms and other scenarios, such as 0.3 tons of low-voltage electric boiler about 28,000 yuan.

Medium-sized industrial model (1-10 tons/hour): the price range is 80,000-800,000 yuan, including about 120,000 yuan for a 1-ton automatic electric boiler and about 500,000 yuan for a 5-ton high-pressure model.

Large customized models (more than 10 tons/hour): The price of a single unit exceeds 1 million yuan, mainly used in electric power, chemical and other industries, and needs to be designed according to user parameters.

8. What are the application fields of electric steam boilers?

Industrial production: Cooking and sterilization in food processing, material reaction in the chemical industry, maintenance and heating in building materials production, etc., especially suitable for the pharmaceutical industry with high requirements for steam cleanliness.

Commercial services: Heating and heating in hotels, disinfection and sterilization in hospitals, air conditioning and humidification systems in shopping malls, and small models can flexibly meet the needs of decentralized steam consumption.

9. Summary

Electric steam boiler is an efficient and environmentally friendly energy conversion equipment with the advantages of clean and environmentally friendly operation, intelligent operation, and low maintenance costs. Although the operating cost is relatively high, electric steam boilers are still a good choice in scenarios with strict environmental protection requirements and stable power supply.
