Learn how boilers are applied in the heating industry. A 1-ton hot water boiler generates 600,000 kcal per hour, covering around 10,000㎡ for residential, office, or hotel heating. Actual heating area varies depending on building structure, height, and insulation performance. Modern energy-saving and thermal insulation buildings achieve better heating efficiency compared to traditional buildings.

A condensing gas boiler uses a condenser to recover waste heat from flue gas, raising the inlet water temperature and achieving thermal efficiency up to 98%. Compared with traditional boilers, it saves fuel, reduces costs, and delivers outstanding energy-saving and environmental benefits. Today, condensing gas boilers are widely used in industrial production due to their high efficiency, long-term reliability, and market competitiveness.

Understand the key differences between biomass boilers and coal-fired boilers in the industrial sector. Biomass boilers use renewable fuels like straw, corn cobs, wood chips, and pellets, offering cleaner emissions and environmental benefits. Coal-fired boilers, while reliable and adaptable with mature technology, produce more dust, sulfur oxides, and nitrogen oxides, leading to pollution concerns. Learn about combustion process differences, boiler design adaptations, efficiency, and the future trend of clean energy boilers.

Gas-fired boilers offer significant advantages over traditional coal-fired boilers. With combustion efficiency above 99%, low sulfur dioxide emissions, and zero fly ash, they are highly environmentally friendly. Gas boilers heat up quickly, are easy to start and stop, and feature a high degree of automation. They eliminate the need for coal yards, slag removal systems, and reduce labor intensity and transportation pressure. With stable calorific value and precise flow control, gas-fired boilers ensure reliable, efficient, and cleaner operation for modern heating and industrial needs.

Discover 15 proven methods to increase boiler efficiency and reduce operating costs. Practical tips include lowering stack temperature, installing an economizer, tuning the burner, using variable frequency drives, insulating valves, cleaning the fireside and water side, preheating combustion air, returning condensate, recovering blowdown heat, controlling blowdown rate, reducing excess air and carry-over, surveying steam traps, and cutting steam usage. Improve fuel utilization, extend boiler life, and achieve energy savings with these strategies.

Insufficient combustion in boilers reduces efficiency, increases gas consumption, and produces excess carbon monoxide. To solve this, oxygen control and precise air–gas ratio adjustment are essential. Installing a flue gas probe to monitor oxygen levels allows the combustion control system to automatically adjust gas supply, ensuring complete combustion, improved fuel utilization, and safer boiler operation.

Boiler feed water deoxygenation is essential to prevent oxygen corrosion in boilers and water supply systems. Oxygen in feedwater leads to iron oxide formation, scale buildup, pipe wall pitting, increased resistance, and even pipeline explosions. National standards require deaeration for steam boilers with ≥6t/h evaporation and hot water boilers with ≥4.2MW power, ensuring oxygen content ≤0.05mg/L. Proper deoxygenation protects boiler tubes, economizers, and pipelines while avoiding severe economic losses caused by corrosion.

A steam boiler and a steam generator are different in structure, capacity, and inspection requirements. Steam boilers release heat energy through fuel combustion to produce steam with stable temperature and pressure, requiring annual inspection as special equipment. With larger water volume, wide capacity range (1–100 tons), and better steam quality, boilers suit continuous industrial use. Steam generators, with simple structure, small water volume (<30 liters), and fast startup, are modular and ideal for small enterprises with intermittent steam needs.
