Coal Fired Thermal Oil Boiler Introduction

The organic heat carrier boiler refers to a new type of heat energy conversion equipment that carries high-temperature heat conducting oil (also known as hot coal and heat carrier) as its working medium.So the organic heat carrier boiler is also called the thermal oil boiler. The capacity of the furnace is usually expressed as “MW” (megawatt), but may also be expressed as “gw /h” or “10,000 kcal/ hour”, i.e. “104kcal/h”. Organic heat carrier furnace (also known as thermal oil furnace) is widely used because of its advantages of high temperature and low pressure, stable operation. Thermal oil boiler has liquid phase and gas phase.

Coal Fired Thermal Oil Boiler Structural Features

  • The horizontal coal fired thermal oil boiler is a square – box assembly – type forced circulation chain grate boiler. The boiler is composed of the upper body (or upper body + lower body) and the lower grate, which is combined on site.
  • The heating surface of the boiler body adopts the forced-coiled convection heat transfer tube behind the square coil in single or double furnace Chambers.
  • The end of this series of thermal oil boiler is equipped with air preheater, steam waste heat boiler and hot water economizer for waste heat recovery according to users’ use of waste heat, so as to reduce smoke exhaust temperature, improve boiler thermal efficiency, reduce fuel consumption and save energy.
  • According to the fuel characteristics, the boiler convection heat transfer section adopts the measures of high and low misalignment, spacing and arrangement of ash blowing device and ash cleaning device, etc., to reduce the accumulation of boiler ash and improve boiler efficiency.
  • The boiler adopts high quality heat preservation material and special construction technology with good heat preservation effect.
  • The boiler heating surface pipe butt should be fully automatic gas protection welding process and equipment, can be 100% real-time X-ray online detection welding. The welding quality is stable and reliable.
  • Large boilers adopt division integration and field assembly. High integration, quick and convenient field installation.

  • Special design of grate arch, independent adjustment of air chamber, full uniform coal combustion, wide adaptability of fuel.
  • The boiler adopts high quality heat preservation material and special construction technology with small heat loss.
  • Combined with industrial automation control technology, Internet technology, computer software and artificial intelligence technology, the industrial boiler Internet of Things platform is established, which can realize remote man-machine interaction and data sharing, and realize dynamic control.

2. Safe and reliable operation

  • The boilers heating surface of the body adopts the dense coil pipe, and the heating surface is sufficiently arranged, which can effectively reduce the heat load of the pipe surface, and the use of the heat-conducting oil medium is safer.
  • The medium flow is reasonable, the design model for heat conduction oil is low (import) to high (export), the medium gas generated during operation is difficult to stay in the furnace, it can be easily discharged from the system.
  • The heat exchange surface of the furnace adopts double dense row coil tube, the heating surface is fully arranged, the load rises quickly and the load is large.
  • Coal fired thermal oil boiler operation using remote and near – ground multi – control, automatic control and monitoring instruments complete.
  • The convective heat transfer section at the tail adopts special anti-ash structure design, and is equipped with a ash blowing device, so that the operation does not accumulate ash and the heat transfer efficiency is high.

3. Environmental protection and energy saving

Environmental Protection According to local environmental protection requirements, appropriate flue gas treatment equipment is configured to meet environmental protection requirements.
