The reduction of nitrogen oxides in gas-fired boilers is mainly achieved by burners and increasing the furnace size of boilers. In order to help enterprises save costs and reduce nitrogen oxides in gas-fired boilers, low-nitrogen transformation can be realized by configuring appropriate low-nitrogen burners and staged combustion technology plus the flue gas internal circulation technology, and the emission can be controlled to be less than 30 mg/m3.
Reasonable arrangement of igniters in gas-fired boiler can not only obtain ideal ignition effect, but also save ignition fuel. However, due to the different types of fuel and burner, the igniter arrangement of gas boilers is different.
First, let's explain what an industrial oil-fired boiler is. The industrial oil-fired boilers refer to boilers that use oil as the fuel. Generally, they burn diesel oil, special fuel oil for boilers, heavy oil and waste oil, etc. However, due to the rising price of diesel oil and the problem of supply, they are now turning to fuel oil.
The gas-fired boiler is operated by an advanced combustion machine, equipped with automatic gas supply and ignition combustion system, and the gaseous fuel is easy to burn. Therefore, the gas-fired boilers need not be equipped with blower and induced draft fan components.
As an effective tool in the era of environmental protection, gas-fired boilers are favored by all walks of life and widely used in food, paper, building materials, wine, chemical industry and other industries. With the increasing use of gas-fired boilers, there are more and more problems.
As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
The advantages of boiler fueled by the methanol can be concluded as follows:
a. The emission from boiler fueled by the methanol is very environmentally friendly, without sulfur, particulate matter, heavy metals and polycyclic aromatic hydrocarbons.
b. The methanol fuel is quite cost-effective.
c. The operation of boiler fueled by the methanol is safety. Compared with compressed natural gas, liquefied petroleum gas, gasoline and diesel fuel, methanol has the char...
