YLL Vertical Coal Fired Thermal Oil Boiler Coal fired vertical thermal oil boiler use coal as fuel, the heat transfer oils is heated in the boiler first, then the thermal oil flow in a closed loop pipe to the heated equipment and then return to the thermal oil heater again, in this way, the heated object can reach a high temperature (Max. 320?) with indirect heating. It is especially suitable for industies which are flames prohibited Bidragon biomass and wood fired thermal oil heater is high efficient compared with other heating systems. 1. Multi-passes thermal conductive structure to improve the thermal efficiency greatly 2. Horizental tubes can reduce the heat loss. 3. Thicker insulated layer to reduce heat loss by thermal radiation. 4. Intelligent control system makes biomass fired thermal oil boiler operation easier and more simple. Advantage of YLL Vertical Coal Fired Thermal Oil Boiler 1.The oil flow from the lower place to the high place,in this process, the produced gas can easily go out of the system. 2.Automatic feed coal fuel, automatic discharge the slags. 3.Fire grate use independent air chamber, and the air space is larger, so the burning will be more sufficiently.

What is Blast Furnace Gas Blast furnace gas is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value, about 93 BTU/cubic foot, because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable. The rest is mostly carbon monoxide, which has a fairly low heating value already and some (2-4%) hydrogen. It is commonly used as a fuel within the steel works, but it can be used in boilers and power plants equipped to burn it. It may be combined with natural gas or coke oven gas before combustion or a flame support with richer gas or oil is provided to sustain combustion. Particulate matter is removed so that it can be burned more cleanly. Blast furnace gas is generally used to as the raw materials of steam - gas-fired combined cycle power generation. Blast furnace gas fired boiler designed and manufactured in ZG Boiler is suitable for iron, steel, and it is also the best choice of the nation to sustainable development and green economy. Blast Furnace Gas Fired Boiler Structure 1. Using "� " Type Arrangement With whole structure "� " type arrangement, the blast furnace or coke oven gas fired boiler adopts front suspending back supporting, plumbing systems, superheater and other suspended from the roof on the boiler, economizer, air preheater, etc. are arranged at the rear steel shelves, air preheater can be pulled out from the back, which are easy to maintain. 2. Square Chamber Design The furnace is design as square, and the burner is arranged in the corners, using the four corners of the vortex burner ignition, also has a higher temperature of the hot air, combustion gas required to ensure that the temperature field and the aerodynamic conditions not only to ensure adequate fuel gas combustion, but also to prevent the fuel gas and air mixture within the burner. 3. Multiple Security Devices In addition to conventional protection device, the boiler is also equipped with automatic ignition device, flame monitoring device, flame protection device and supply device which automatically cut off the gas when the gas pressure is lower than a certain value and other safety devices
