Asphalt Solutions
We provide an integrated solution for full-set heating, temperature control and waste heat recovery for asphalt mixing plants, which saves energy and reduces consumption, and ensures stable and compliant asphalt production.
1. Solution Overview
Targeting the working conditions of road asphalt mixing production, we provide a complete thermal equipment solution including thermal-oil heating system, combustion heating and waste heat recovery. It covers the whole process of asphalt storage, heating, transportation and mixing, solves industry pain points such as unstable asphalt temperature, high energy consumption and waste of flue-gas heat, and is applicable to various asphalt mixing plant projects.
2. Technical Approach
(1) Precise temperature-controlled heating: Taking thermal-oil heater as the core heat source, it stably supplies high-temperature heat for constant-temperature heating of asphalt storage tanks, conveying pipelines and mixing equipment, preventing asphalt solidification and aging. The temperature is controllable and adjustable to meet process temperature requirements for different grades of asphalt.
(2) High-efficiency combustion system: Equipped with low-NOₓ burners, compatible with multiple fuels such as natural gas and heavy fuel oil. It ensures complete combustion and reduced emissions, adapting to on-site fuel conditions at construction sites.
(3) Waste heat recovery and utilization: Recovers waste heat from high-temperature flue gas of mixing equipment to preheat thermal oil or supply auxiliary process heat, cutting fuel consumption and operating costs.
(4) Safe automatic control system: The whole system is equipped with automatic PLC control with interlock protection against over-temperature and over-pressure, realizing stable unattended operation.
3. Application Scenarios
(1) Asphalt mixing plant projects for road engineering
(2) Heating working conditions for asphalt storage and transshipment
(3) Production of asphalt mixture for municipal roads and expressways
(4) Modified asphalt manufacturing and processing enterprises
4. Solution Benefits
(1) Stable and controllable temperature, avoiding asphalt aging caused by overheating and solidification under low temperature
(2) Waste heat recovery greatly reduces fuel costs
(3) Low-NOₓ combustion meets environmental emission standards
(4) Integrated delivery of complete equipment sets, suitable for on-site renovation and new construction projects
Other Solutions
Heating Solution for Chemical Industry
Heating Solution for Chemical Industry Adopts a closed‑loop heating system consisting of "thermal oil heater + high‑temperature circulating pump + heat exchange for heat‑consuming equipment + automatic control". The organic heat‑carrier furnace heats the thermal oil to 280~350℃. Forced circulation by the high‑temperature circulating pump delivers hot oil stably to heat‑consuming equipment such as reaction kettles, distillation columns and evaporators to achieve precise constant‑temperature heating. It features high temperature‑control accuracy, safe and reliable operation under atmospheric pressure, and thermal efficiency ≥90%. Suitable for heating processes in petrochemicals, fine chemicals, printing & dyeing, oil & fat, asphalt and other industries.
