Heating and hot water daily is an important basis for maintaining the northern region of the normal operation of enterprises; for Legal Daily organs and units, the hot water boiler is one of the indispensable energy equipment. Currently, work is facing north Heating equipment and facilities aging, increase energy conservation and environmental protection requirements and other issues. Daily logistics-related legal person responsible for improving the overall level of heating units, and the response advocated by the national energy saving, plans to purchase energy-efficient heating boiler. Considering the increasingly stringent environmental policy, Legal Daily authorities decided to use natural gas as boiler fuel. Fast boiler for 20 years, specializing in the production brand boiler, which had been successfully assisted more than Beijing enterprises and institutions, to provide clean heating. The party technical consultant fast boiler based on actual usage Legal Daily units, providing commercial condensing units 99KW vertical 1 hot water boiler.
The key to avoiding that the furnace excess air is reasonable air distribution and monitoring control means which adapts. Monitoring means are CO2 or O2 content measurement method for measuring oxygen gas boiler is usually carried out, because the combustion of gas boiler a slight positive pressure, the seal is easy to solve the problem, the oxygen content is measured more accurately reflect the excess air coefficient values. Oxygen measurement techniques now commonly used zirconia-type oxygen analyzer constant temperature, continuous on-line measurement of the oxygen content of the flue gas. The flue gas oxygen content as a reference, the correct air-fuel ratio adjustment, a low oxygen combustion.
Clear oil-fired boiler pressure gauge: pressure gauge is displayed in the oil-fired boiler media is the main safety accessories boiler boiler operator in the operation closely watched. Pressure gauge not only to check regularly transferred to the metering sector, but also in the boiler operation, done regularly to gauge back to zero test, to verify the reliability of the sensitive pressure gauge to ensure the safe operation of the boiler. Procedure: (1) gauge twisted way cock closed trap passage, the air passage is opened and the pressure gauge; gauge the pressure relief, the pointer back to zero; if (2) Check the pointer back gauge to zero limiting, the staple; (3) back to zero if limiting, nails, pressure gauges should twisting three-way valve, pressure gauge and close the air passage, slowly open the trap passage and the pressure gauge, the fuel gauge is displayed pressure in the boiler; (4) if the pointer can not return to zero (including a staple stop finite and infinite stopper nails), the pointer should be checked from the zero bit value exceeds a predetermined tolerance gauge; (5) exceeds a predetermined pressure gauge allows error, the pressure gauge should be replaced; (6) If the gauge does not exceed the predetermined allowable error, considered acceptable, the pressure gauge should twist way cock, pressure gauge and close the air passage, slowly open the trap passage and the pressure gauge , pressure gauge immediately displayed in the oil-fired boiler.

Because such gas boiler equipment belongs to gas energy, so the cost is relatively low, especially compared with coal-based boiler, in the cost have been reduced, has become among the many companies will attention to the point. Not only that, now the manufacturers, because in the production of technical improvements, so this device, you can have a system of automatic control, added safety protection devices, etc., so when during use, do not worry about the safety of one of the problem.
Most modern boilers are not controlled by an ON/OFF switch as they did in the past if automatic. A pressure switch with a cut out at high pressure and a cut-in at some span below the high cut-off is a tad old-fashioned, though still used in domestGet a Quote

For example, if a process of which steam consumption is only 5% of boiler output is turned on rapidly (such as with an on-off valve), the system demand can easily increase by 15% or more until the process reaches a steady state of operation. When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly.Get a Quote
2020-6-6 · What pressure should my boiler be? Generally, your boiler pressure should be between 1 and 2 bar. However, read your boilers manual or ask your heating engineer for the required pressure for your particular model. To check your boilers pressure, you need to locate the pressure gauge on your boiler.Get a Quote
Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to theGet a Quote
The boiler operating control is set at the desired steam pressure of the boiler. On-off steam systems for comfort heating are usually set for an average of 2 lb. of steam pressure. The operating control is an automatic one that will cycle the boiler between the settings of the pressure control asGet a Quote
The pressure gauge needle indicates the actual pressure of the system. A green zone shows the correct pressure range, while a red zone shows the critical zone.: A red needle serves as a marker, while a black needle corresponds to the actual pressure.These two needles should be on top of one other.: In some boiler models, the water pressure is given by indicator lights on the control panel.Get a Quote
A steam accumulator is a pressure vessel (or tank) with internals and controls, that can reduce the fuel consumption, maintenance costs and increase the service life of your boiler by stabilizing the steam draw conditions, but it cannot make up for shortcomings in total boiler capacity. The accumulator acts as a flywheel or capacitor, storing energy for short periods until the process requires it.Get a Quote
The Weil McLain boiler has an auto-fill valve that is designed to prevent the boiler from accumulating too much water pressure. However, you must set this valve to the proper limit or else it will not shut off the water supply early enough. Learn how to manually reduce theGet a Quote
A kilogram of steam at a higher pressure occupies less volume than at a lower pressure. It follows that, if steam is generated in the boiler at a high pressure and also distributed at a high pressure, the size of the distribution mains will be smaller than that for a low-pressure system for the same heat load. Figure 10.1.2 illustrates this point.Get a Quote

If we are speaking of home steam heating boilers the pressure is controlled by a device known as a Pressuretrol which can be adjusted for cutout or cut in pressure and differential normally. If your pressure seems to stay too high,, keeping the boGet a Quote
2020-6-1 · The boiler pressure will normally rest at 1 bar when cold and rise to 2.5 bar when in full use. On many newer models, the boiler will be equipped with a cutoff switch to prevent damage to the heating system; should the pressure fall too low or too high, the boiler will shut off. You can reduce the water pressure in your system by bleeding theGet a Quote
Boiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm 2), the requirement of the CPU is usually avoided.Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.Get a Quote
