Different types of oil-fired boilers have different equipment composition. ZOZEN Boiler describes the composition of oil-fired boiler equipment aiming at WNS series and SZS series.
Boiler water circulation refers to the circulating flow of water and steam-water mixture on the evaporating heating surface of boiler. What is the working principle of the latest water circulation system of boiler?
The rated output of boiler refers to the maximum sustained output of industrial boiler under rated parameters (pressure and temperature) and certain efficiency. For steam boilers, the rated output is also called rated capacity, and the unit is t/h (tons/hour); For a hot water boiler, the rated output of the boiler is also called the rated thermal output, and its unit is MW.
Heavy oil for industrial boilers, namely fuel oil, is mainly made from petroleum cracking residue and straight-run residue, which is characterized by high viscosity and contains many non-hydrocarbon compounds, gums and asphaltenes. Among them, the viscosity of industrial boiler special oil is an important performance index of fuel oil, and it is also the main basis for dividing fuel oil grades.
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.
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?
