The purpose of boiler pipe flushing is to use the self-generated steam of boiler to flush away the rust, welding slag, iron filings, ash scale and oil scale and other impurities in the superheater, reheater heating surface pipe and steam pipeline, otherwise the following hazards will occur when supplying steam to the steam turbine:
(1) The high-speed steam flow carries sundries and impacts the turbine blades, forming a large number of pits, which will cause the blades to break in severe...
Attention should be paid to the monitoring of flame during boiler startup, and the following combustion adjustment work should be done well:
(1) Correct ignition. Before ignition, the furnace is fully ventilated. When ignition, put the ignition device (or torch) into operation first, and then turn on the oil gun.
(2) Put the burner diagonally into use, pay attention to switch in time, observe the proper ignition point of the burner, and strive to distribute the flame evenly in the furn...
The boiler system consists of boiler body, energy-saving equipment, instrument valves, water treatment and control system, and some will add economizer. Because many users don't know what the working principle of boiler economizer is, here ZOZEN Boiler will answer for you.
Working principle of boiler economizer
Boiler economizer, as its name implies, is a boiler device for saving energy, which is generally installed at the tail of boiler flue and used to recover the waste heat of high ...
Gas-fired steam boiler refers to a steam boiler with rated evaporation capacity of 10 tons. Under normal circumstances, a 10-ton gas-fired boiler can produce 10 tons of steam in one hour. In the process of running a 10-ton gas-fired steam boiler, try not to overload it, otherwise the boiler will easily break down and even reduce its service life.
Which is the best choice for a 10-ton gas boiler?
Gas-fired boilers have many advantages. The emission of nitrogen oxides from gas-fired boil...
I. Water content
The water content of different fuels varies greatly, depending on the fuel type and storage method. In order to maintain the combustion stability of biomass boiler fuel, it needs to be aired before use (a dry shed should be added when conditions permit). The increase of water content will reduce the heat storage temperature of the furnace and increase the incomplete combustion of fuel in the combustion chamber. Excessive water content is the main reason why the national energy ...
The common methods for boiling the gas-fired boiler:
1. Sodium carbonate (Na2CO3) or trisodium phosphate (Na3PO412H2O) and other drugs are used, and the dosage is calculated as per cubic meter of boiler volume, with the former being 5 kg and the latter being 3 kg;
2. Close the front manhole, hand hole and main steam valve (main water outlet valve), open the manhole of the upper drum, inject the prepared solution into the drum at one time, then close the manhole and open the emptying valve...
The combustion equipment of gas-fired boiler is burner and furnace. Before ignition, the burner should purge the furnace first, and then enter the ignition process. Why should the gas-fired boiler be purged before ignition?
Causes of purging before ignition of gas-fired boiler
Exhaust the pulverized coal and combustible gas that may accumulate in the furnace, flue and air preheater (or clean the pulverized coal accumulated in the primary air duct) to prevent deflagration during ignitio...
The design and construction of boiler room is also a very important point in the safe use of boiler. The gas supply, combustion, inspection and other items of the boiler should also comply with the boiler room design code. As many users have consulted the question whether pressure boilers can be installed in the basement, ZOZEN Boiler here will give you a professional answer.
Can the pressure-bearing boiler be set in the basement? It is necessary to refer to the relevant design codes of...
