The boiler is a kind of special equipment and its export to the international market and competitiveness in the world lie in its conformity marks from international authoritative certification bodies.
ZOZEN has extended its sales network from the entire Asia to Africa, Oceania, Eastern Europe, America and other regions over the years. ZOZEN also has obtained important international certifications such as ASME, PED, DOSH, IBR, and has been qualified for independent import and export of industrial boilers. Its various series of boiler products have been sold to more than 100 countries and regions around the world.

In the Density vs temperature figure (°C), you se that the light blue line represent this fuel oil. Then, use the light blue line in the Fuel oils volume correction figure (Density@Observed T/Density@15°C). At 200°C the correction factor is 0.859. The volume of your fuel oil at 15°C is 100liters*0.859 = 86 liters.

Jan 13, 2010· Fuel Oil Temperature and Boiler Operation. Fuel oil is one of the fossil fuesl used in boilers to generate steam. The hydrocarbons in fuel oil need heating for reducing the viscosity to a favorable level for handling and firing. Depending upon the composition of the oil, the effect on performance of boiler can be judged.

generally consistent for all types of boilers: an increase in flame temperature, oxygen availability, and/or residence time at high temperatures leads to an increase in NOx production. Fuel nitrogen conversion is the more important NOx-forming mechanism in residual oil boilers.

The temperature of boiler fuel oil depends on its viscosity. I’m a shippy person, so again for ships a Viscometer is fitted in the fuel line to maintain the viscosity at the right value for burning. With IFO180 this temperature is around 120C, higher for IFO380. Again it will be the same of similar for land use boilers.

The viscosity of oil varies with temperature: the hotter the oil, the more easily it flows. Indeed, most people are aware that heavy fuel oils need to be heated in order to flow freely. What is not so obvious is that a variation in temperature, and hence viscosity, will have an effect on the size of the oil particle produced at the burner nozzle.

Jul 14, 2017· Unless the boiler is smart enough to raise the supply temperature by zone, you probably want 180-degrees going into the indirect to get reasonable recovery rate. Most radiators are desgined for that temperature, too. To keep the thing from short cycling (it works best if it runs for awhile), you might want to try something like 200-160.

(An oil viscosity chart is provided later in this section in Figure 6.) Select the line corresponding to the required flow, and the column corresponding to the nominal pipe size. The intersection will give the pressure drop in psi per 100 feet of equivalent pipe length. For example, a typical No. 2 fuel oil has a viscosity 40 SSU. A 500 hp boiler

Dec 05, 2004· Heating oil condenses at a lower temperature than petroleum jelly, bitumen, candle wax, and lubricating oil, but at a higher temperature than kerosene, which condenses between 160–250 °C (320–482 °F). The heavy (C20+) hydrocarbons condense between 340–400 °C (644–752 °F).

Sep 19, 2018· Oil burns hotter than natural gas, delivering more heat per BTU compared to other heating sources. Less Upfront Cost Heating furnaces that use oil cost 10% – 25% less than the ones that use natural gas. Safer to Store and Use Despite the fact that oil is flammable, it will not explode in case of an accident.

Heating oil is safer to store and use Heating oil doesn't ignite until its temperature reaches 140 degrees, when it vaporizes. So, if you dropped a lit match into heating oil, it's like dropping it into water, the flame extinguishes on contact. Heating oil also does not produce carbon monoxide.

A greater heat-release rate and complete combustion within the furnace tube are achieved, which causes reduction in combustion-chamber temperatures of not less than 110°C, these temperatures being maintained below the critical 925–955°C level.

The kinematic viscosity of No. 2 fuel oil at 40°C= 1.9 - 3.4 mm 2 /s The viscosity of No. 2 fuel oil at 21.1°C is also given as 3.0 - 7.4 cSt or 36-50 SSU. #3 fuel oil is a distillate fuel oil that is not in wide use. #4 fuel oil (bunker oil) is used in large stationary engines, power plants, and very large commercial boilers.
