• Biomass and Heat Transfer Oil Boilers:
Hangzhou Zhongneng Boiler Co., Ltd. has pioneered a range of eco-friendly solutions tailored to modern industrial demands. Among its standout products is the biomass boiler, designed to utilize renewable fuels such as wood chips, straw, hemp stalks, and fruit shells—byproducts often discarded or burned in open fields. In 2023, Zhongneng delivered a 1500 kg/h biomass boiler to a rural paper pulp factory in Fujian Province, replacing a high-emission coal-fired unit. The new system not only eliminated visible smoke emissions but also reduced operating costs by nearly 40% due to lower fuel prices and improved combustion efficiency. The integrated combustion technology, capable of sustaining temperatures above 1400°C, ensures near-complete combustion with ash residue appearing off-white—proof of minimal unburned carbon. Meanwhile, the heat transfer oil boiler series has become a preferred choice for industries requiring precise temperature control without high-pressure risks. A pharmaceutical plant in Guangdong adopted a WNS-series pressurized hot water boiler using heat transfer oil, achieving stable output at 180°C with ±1°C accuracy. This level of precision is critical in active ingredient synthesis processes, where even minor fluctuations can affect product quality. The low operating pressure (typically under 1.0 MPa) and excellent heat transfer efficiency have led to a 25% reduction in energy consumption compared to traditional steam systems. These case studies demonstrate how Zhongneng’s advanced technologies deliver both economic and environmental benefits, positioning the company as a leader in green industrial heating solutions.
• Coal-Fired and Oil/Gas-Fired Boilers:
Zhongneng Boiler’s coal-fired and oil/gas-fired boilers exemplify the balance between traditional reliability and cutting-edge efficiency. The LHC series vertical double-grate reverse combustion coal-fired boiler has been widely adopted by small and medium-sized enterprises across China’s manufacturing belt. In one notable case, a food processing plant in Shandong replaced its aging horizontal boiler with a Zhongneng LHC-1.2 model. The new system offered faster start-up times, higher thermal efficiency (up to 84%), and easier maintenance thanks to the open furnace body design. Maintenance staff reported a 60% reduction in cleaning time per cycle, directly improving uptime and productivity. On the oil and gas side, the SZS-series oil/gas-fired steam boiler has proven ideal for large-scale operations. A chemical park in Jiangsu Province installed three 30-ton/h SZS boilers to meet fluctuating steam demands across multiple production lines. Equipped with advanced combustion control systems and optimized flue gas paths, these boilers maintained consistent steam quality while reducing NOx emissions by 45% and saving up to 30% in fuel usage annually. Notably, the pressure control logic—switching from high-fire to low-fire at 0.9 MPa and back at 0.8 MPa—ensured stable operation without surges, preventing equipment stress and extending component life. These real-world deployments highlight Zhongneng Boiler’s ability to deliver scalable, efficient, and durable solutions that align with national energy-saving policies and global decarbonization goals.
