Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
Boiler safety accessories are indispensable parts of boiler operation, mainly refer to accessories such as pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve, etc. These accessories are extremely important to the safe operation of boilers, especially pressure gauges, water level gauges and safety valves, which are the basic accessories for ensuring the safe operation of boilers. Therefore, they are often referred to as three safety accessories of industrial boilers.
Boiler antifreeze, as its name implies, is a kind of regulator that can prevent the water in the boiler or boiler circulation pipe from freezing and inhibit the formation of scale. Boiler antifreeze contains a special corrosion inhibitor, which can be used and stored for a long time, keeping its characteristics unchanged, and will not damage the metal parts of the boiler.
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.
Boiler steam pressure control refers to maintaining the steam pressure of boiler drum by adjusting the fuel control system. Its basic task is to adapt the heat provided by fuel combustion to the steam load of boiler drum. At the same time, it is necessary to ensure the safe and economic operation of boiler drum and meet the requirements of environmental protection.
To buy dust removers for coal-fired boiler with good cost performance, we should first know more about the manufacturer, quotation and market. After all, a good vendor can bring more help to customers. Therefore, determining the sales manufacturer will be the focus of purchasing coal-fired boiler dust collectors. Coal-fired dust remover has high efficiency and will have more outstanding performance in use. Of course, when selecting products, we should know the quality of coal-fired boiler dust removers, so as to choose equipment with reasonable price and stable performance.
The price difference of coal-fired boiler dust remover is mainly due to the different specifications and models.
According to the characteristics of biomass fuel, the biomass boiler produced by ZOZEN Boiler has been specially designed in structure, which has taken the lead in solving the problems such as furnace arch collapse, furnace door burn-out, hopper fire and stopper coking.
There are many kinds of industrial boilers, for example, according to the boiler pressure, it can be divided into negative pressure boiler and micro positive pressure boiler.
