MFT means the main fuel trip. To put it simply, when the protection signal is activated, the control system automatically cuts off the boiler fuel system and links the corresponding systems and equipment, so that the whole thermal system can be safely shut down, the boiler can be protected, and the fault can be prevented from further expanding.
The ignition system of gas-fired boiler adopts high-energy igniter, which belongs to low-voltage capacitive discharge device. Its main structure is composed of nddh high-energy igniter, nddz igniter and nddl shielded ignition cable.
For the dust removal of biomass boiler, centralized or decentralized dust removal system are generally selected according to the process flow, and available dust can be recovered as much as possible under the conditions of process permission. The core of dust removal system is various types of dust collectors, including bag filter, electrostatic filter and electric bag filter.
The ignition of industrial coal-fired boiler needs to be operated steps by steps, and the ignition operation is different according to the specific model of industrial coal-fired boiler. Grates of industrial coal-fired boilers are usually divided into manual grates and mechanical grates. Here, according to the different grates, the correct ignition steps of industrial coal-fired boilers are introduced in detail.
In the industrial boiler industry, it is generally divided into four grades: A, B, C and D according to the production qualification license grade, among which, when purchasing boilers, users often consider Grade A boiler manufacturers. What is a grade A boiler?
The so-called tower boiler refers to a boiler with a furnace at the lower part and a convection flue at the upper part. The features of domestic tower and tanks include the following aspects.
In the process of the development of national economy, the importance of boilers is self-evident. The so-called boiler is a device that uses the heat energy released by fuel incineration to heat water or other media, so as to obtain steam, hot water or other media with specific parameters (temperature and pressure).
Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
