Advantages and Limitations of Oil-fired industrial Boiler

Introduction

In the industrial field, oil-fired industrial boiler is the key heat energy supply device. It provides power and t2hermal support for industrial production by burning fuel oil (such as diesel, heavy oil, etc.) and converting water into steam or hot water. This kind of boiler is widely used in chemical industry, textile, food, medicine and other industries, and plays an important role in ensuring the stable operation of industrial production.

The Overview of Oil-fired Industrial Boilers

Oil-fired industrial boiler is a kind of industrial heat energy conversion equipment using fuel oil as fuel. It mainly consists of combustion system, steam-water system, control system and auxiliary equipment. The combustion system is responsible for mixing the fuel with the air and burning it fully, The steam-water system uses this heat to heat water into steam or hot water; the control system is used to regulate the operating parameters of the boiler. To ensure safe, stable and efficient operation; auxiliary equipment to support the normal operation of the boiler. According to different classification standards, there are many types of oil-fired industrial boilers, such as diesel boilers, heavy oil boilers, etc.

Advantages of Oil-Fired Industrial Boilers

1. Easy availability of fuel: Adequate supply of fuel in the market, easy purchase and transportation It does not require complex storage and transportation facilities and has advantages in areas with limited fuel supply conditions.
2. High combustion efficiency: Fuel combustion performance is good, mixed evenly with air, combustion efficiency can generally reach more than 80%. Can effectively improve energy efficiency.
3. Rapid start-up: Oil-fired boiler start-up without complex ignition and heating process, can quickly reach the operating temperature and pressure, Meet emergency heat requirements.
4. Modern oil-fired industrial boilers are equipped with advanced automatic control system, which can automatically adjust combustion, water level, pressure, temperature and other parameters. Reduce manual operation, improve stability and safety.
5. Small floor area: Compared with coal-fired boilers, oil-fired boilers are compact in structure and do not require large amounts of fuel storage space. Suitable for industrial plants with limited space.

Limitations of Oil-fired Industrial Boilers

1. High fuel costs:High fuel prices and international oil price fluctuations, long-term use will increase production costs, Compared with solid fuels such as coal, the pressure of operation cost is greater.
2. Fuel quality requirements: Fuel quality has a great impact on the operation of the boiler. Impurities and moisture will lead to incomplete combustion, nozzle blockage, boiler corrosion and other problems, need strict filtration and purification treatment.
3. Environmental pollution problems: Fuel combustion will produce sulfur dioxide, nitrogen oxides, smoke and other pollutants, if not treated will cause environmental pollution, Does not meet environmental requirements. Fuel is inflammable and explosive, and safety regulations should be strictly observed to prevent leakage, fire and explosion. And the storage condition request is high, increases the difficulty and the cost.

Cost Analysis of Oil-Fired Boilers

The initial investment cost: It includes the purchase cost, installation and commissioning cost of the boiler body, burner, control system, auxiliary equipment. Compared with coal-fired boiler, oil-fired boiler has lower initial investment because of its simple structure and no need of complex fuel storage and transportation system. The initial investment of small oil-fired boilers is about $5600 to $14,000, and the initial investment of large oil-fired boilers can reach $280,000.

Operating costs: Including fuel costs, water charges, labor costs, maintenance costs, of which fuel costs accounted for more than 70%. taking 10t / h oil-fired steam boiler as an example, the fuel consumption is about 700kg per hour, the hourly fuel cost is about $784. In addition, other costs will increase with running time and intensity.

The Applicable scenarios of Oil-fired Boiler

• Small and medium-sized enterprises:Oil-fired boiler is a good choice for small and medium-sized enterprises, such as small chemical industry, food processing, garment factory, etc. The utility model can meet the basic heat demand, and the initial investment and installation cost are low.
• Fuel supply restricted areas: Where solid fuels such as coal are in short supply or difficult to transport, but where fuel is in sufficient supply, the oil-fired boiler can guarantee the heat used in industrial production.
• In areas with low environmental protection requirements:In areas with low environmental requirements and lax pollutant emission control, oil-fired boilers can still be used.

Future Trend of Oil-fired Industrial Boiler

• More advanced environmental technologies: such as high efficiency desulfurization, denitrification, dust removal equipment and low nitrogen combustion technology, will be developed and applied in the future. Make oil-fired boiler more environmentally friendly, meet environmental standards.
• Combined with new energy sources: Oil-fired boilers may be combined with new energy sources such as solar energy and solar energy to form a hybrid energy system. For example, when there is solar energy to use solar energy to heat water, reduce fuel consumption and improve energy efficiency.
• Intelligent and digital development: The future of oil-fired boilers will be more intelligent and digital, through sensors, Internet of Things technology and big data analysis, It can realize real-time monitoring, remote control and fault diagnosis, improve operation efficiency and safety, and reduce operation cost. The crude oil-fired industrial boiler is an important industrial thermal equipment.
