Learn how to properly maintain hot water boilers during shutdown to prevent corrosion and extend service life. After cooling, remove ash deposits, ensure natural ventilation, and use desiccants such as quicklime to control moisture. For shutdown periods less than one month, wet maintenance is recommended; for more than one month, dry maintenance is required. Discover detailed steps for cleaning, drying, applying anti-corrosion paint, and preventing flooding damage, ensuring boilers remain in safe and efficient condition during long-term downtime.

Central heating boilers offer significant economic and environmental advantages compared to wall-hung boilers. With thermal efficiency as high as 80%–90%, central heating can save around 30% of energy while providing continuous, safe, and uniform heating. Equipped with advanced dust removal systems and high-efficiency collectors, large capacity heating boilers effectively reduce urban pollution. Central heating is mature, cost-effective, reliable, and ensures 24-hour comfort for residential and commercial users.

Learn the main causes of biomass boiler explosions and how to prevent them. Common risks include furnace combustion and explosions caused by improper ignition and poor purging, overpressure accidents due to failed safety valves, pressure gauge malfunctions, and poor manufacturing quality. Explosions can also occur under normal operating pressure when corrosion, material defects, welding flaws, or illegal water intake damage the pressure components. Regular inspection, maintenance, and proper operation are essential to ensuring safe biomass boiler performance and preventing accidents.

An Indonesia customer has ordered a 2TPH LPG gas fired steam boiler, now completed and shipped for use in a rubber gloves production line. Bidragon gas-fired steam boilers feature a horizontal wet-back structure, compact layout, micro-positive pressure operation, and an integrated fin-type economizer to significantly improve thermal efficiency. Available capacities range from 1TPH to 60TPH, including 2TPH, 3TPH, 4TPH, 6TPH, 8TPH, 10TPH, 12TPH, 15TPH, and 20TPH, making them suitable for diverse industrial steam applications.

A long-term Honduras customer has placed a second order for a 2400kW thermal fluid heater after the first hot oil boiler purchased in 2015 has been running smoothly for 8 years. To expand production capacity, the customer chose the same reliable boiler model with an advanced PLC control system. Considering rising sea freight costs from China to South America after COVID-19, Bidragon advised the customer to order only the boiler body while sourcing accessories such as the chimney locally, helping save shipping expenses and ensuring cost-effective delivery.

Our thermal oil heater system is fully automatic, capable of controlling working status and temperature without manual intervention. An expansion tank installed at the highest point of the system absorbs the thermal oil’s expansion during heating and compensates oil back when it cools and shrinks. This ensures stable pressure and safe, efficient operation. The expansion tank is a critical component for maintaining balance and reliability in the thermic oil furnace system. Contact us to learn more about how our automatic thermal oil heating systems work.

Discover the key reasons for large gas consumption in gas boilers, including increased boiler load and reduced thermal efficiency. Learn how scaling, fouling, air leakage, low gas quality, and burner adjustment failures affect fuel consumption, heat transfer, and combustion efficiency, with practical inspection and troubleshooting methods.

Learn why steam boilers discharge sewage and how to calculate the boiler blowdown rate. Discover the importance of blowdown in removing salts, water slag, and impurities to maintain steam quality, prevent scaling and corrosion, and ensure safe boiler operation. Understand the difference between regular blowdown and continuous blowdown, plus the formula for calculating blowdown rate.
