Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the boiler, and the operation is simpler and more intuitive.
Conventional low nitrogen low nitrogen gas boiler combustion technology mainly focus on how to reduce the combustion temperature to reduce the thermal nitrogen oxides (NOx) generated carried out, the main techniques include staged combustion, premixed combustion, flue gas recirculation. 1, a fuel staged combustion / combustion air staging thermal NOx amount largely depends on the level of the combustion temperature. In the equivalent ratio of the combustion temperature reached the highest value in the case 1, the combustion under lean or rich combustion cases, the combustion temperature will fall much. Using this principle to launch a staged combustion technology.
Szs structural features and gas hot water type water tube boiler of a hot gas pipe sz series of drum water boiler waterwall convection bank smoke condensate recovery chamber and the fuel combustion furnace, the flue gas convection bank into the chimney flue gas condensation recovery. Slight positive pressure of the fuel combustion in the furnace, high temperature flue gas enters the flue turn back along the furnace tube bundle, through pre-compression into a second cigarette bundle 180 enters the second bundle. After the convective heat transfer, flue gas emissions into the atmosphere. A corrugated structure with full combustion furnace, the flue gas only enhance the disturbance, increased radiation heat transfer area, increases the rigidity of the furnace, effectively reduces the expansion stress of the hearth, increase the heat transfer effect. It also promotes the combustion of fuel in the furnace, using a pre-expansion, all welded, expanded advanced technology, both to prevent corrosion of the pipes a gap, but also improves the welding strength, using threads having a high heat transfer coefficient of smoke tubes improve convective heat transfer. Reducing the exhaust gas temperature, the thermal efficiency of the boiler increase. Features szs type gas exact capacity of hot water boiler oversize 1, reasonable structure and layout of the boiler, the boiler can be assembled 10 tons shipped. 2, a large number of heating zones. Boiler heating area, an output; 3, advanced PLC control system, clear, practical. 4 ,. using advanced imported burner, fuel burn rate, reduce the cost of enterprise economy. 5, the structural design of the boiler is reasonable, low requirements for the construction of the boiler room, boiler selected according to the actual conditions, reduce procurement costs.
When purchasing gas boiler first thing to note what is? No matter what industry or in life should be to use a variety of gas, which requires us to buy gas boiler must be carefully. Otherwise, once the purchase to low quality or other problems of a gas boiler when the consequences are very serious, and we buy gas boilers should first be noted that when the surface of the problem. One, first of all we should know the main role is to provide a gas boiler heat for us, so when buying gas boiler should want to see the surface of the packaging material. Select the time try to choose whole body is made of glass wool, glass wool insulation effect because this material is very good, and very light weight. As a result there is a lot of heat in the gas boiler when it will not be lost, once the heat of the gas boiler will not be able to provide more rapid loss of heat energy we need for us, the working efficiency will rapidly decline, but also a waste more fuel. Second, we must consider the size and aesthetic effect, the best choice for white color board packaging when buying gas boiler, it will not only look beautiful at the same time that white color board packaging insulation effect is very good. There is a gas boiler volume size of the problem, if you need a place that can be placed in the position it is very important, if the purchase volume is too large or too small, affect the appearance at the same time will cause unnecessary trouble.
Indirect hot water cylinders powered by central heating boilers tend to require a smaller capacity due to the fact that a boiler has more power available than a standard 3kW immersion heater. The larger the boiler the quicker the reheat time.Learn More
Water heating 17% Why consider water heating options? Hot water use is the second largest portion of energy utility costs, after home heating. Water heating represents 15 to 25 percent of your household energy bill and may become a larger portion if you upgrade the energy efficiency of your home and its space heating and coolingLearn More
Maximizing Small-Boiler Efficiency. The second point relates to the fact that the efficiency of a condensing boiler increases as load decreases. A boiler receiving 90-F return water and operating at 100-percent load has a thermal efficiency of about 90 percent (Figure 1). For the same boiler operating at 25-percent load,Learn More
Complete the equipment settings and application sizing fields to have StateSize calculate the estimated hot water loads. When ready click the "Continue" button to view the recommended State heaters for your project.Learn More
Debunking the myths about condensing boilers "A Condensing boiler is only efficient when fully condensing." Given that a condensing boiler bears a large heat exchanger, it does not have to condense at full capacity in order to be efficient.Learn More
Prescriptive Gas rebates will be offered for Hot Water Boilers (Condensing and non-condensing), Commercial Water Heaters and various heating system improvements, high efficiency furnaces,high efficiency unit heaters that are either: power vented (83% efficiency), condensing (>= 90% efficiency), or low-intensity tubeLearn More
Air exit tanks on heating boilers and circulator pump mounting location - some heating boilers use an air exit tank mounted on the hot water header above the heating boiler to combine the function of an Expansion Tank with the Air Bleeder Valve or air purge valve to rid the hydronic (hot water) heating system of un-wanted air. Air in theLearn More
The heating side of the boiler can be adjusted from the front of the boiler as can the domestic H20, Heating range is 85 degrees - 180 degree. As with any condensing boiler they really are only at there maximum efficiency when condensing (less than 135 degrees).Learn More
Steam has a few more BTUH capacity than 180 hot water. A hot water heating coil will be larger than a steam coil. Plain and simple. If you could retrofit the steam system, the heating coil will not heat the air properly.Learn More
Aug 30, 2002 · Multiple boiler systems are exceptionally well suited to systems that combine space heating with high but intermittent demands for domestic hot water. Consider a situation where the hot water demand is 15 gallons per minute heated from 50 to 120 degrees F. This works out to a heating rate of 525,000 Btu/hr!Learn More
Hot water boilers installed above radiation level must be provided with low water cutoff device either as part of boiler or at time of boiler installation. 2. When boiler is connected to heating system utilizing multiple zone circulators, each circulator must be supplied with flow control valve to prevent gravity circulation. 3.Learn More
hot water requirements . When you are shopping for a gas boiler, it is of top importance to find the one that your home really needs, and this is when a gas boiler size calculator is going to help you out.

Jan 07, 2003 · Don't build "microloading" into your systems. Many such systems have controls that fire the boiler when any of these zones call for heat. The result can be a 150,000 Btu/hr heat generation rate combined with a 5,000 Btu/hr heat dissipation rate, and four or five gallons of water in between to soak up the excess Btus.Learn More
Aug 19, 2013 · Boiler sizing and indirect water heaters.
