Venezuela Gas Fired Steam Boiler


Venezuela Gas Fired Steam Boiler

Fuel gas control step and the blowing process air volume of the total fuel gas venezuela fired steam boiler steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.

If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:

1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.

2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.

Maintenance of oil-fired boiler! What oil-fired boiler include? Fuel oil-fired boiler comprising a boiler water, hot water boiler fuel, the fuel heating boiler, oil bath boiler, and venezuela fired steam boiler fuel, gas oil refers to the boiler fuel (such as diesel, kerosene), heavy oil, residual oil or crude oil fired boilers. Maintenance of oil-fired boilers? After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler.

After the project identification, party fast technical staff soon made contact with our company, to our installation, commissioning, to ensure the look normal, stable use during boiler operation. Thanks fast boiler professional technical support and good service, I provide a lot of help for the textile dyeing and finishing production company. --customer feedback
