Modulation (the capacity to vary the boiler output) is a key concern for biomass steam boilers. Generally biomass boilers will only modulate to 40% of their capacity. A typical oil burner will modulate to 20%, and with the installation of multiple burners, oil boilers can modulate to very low output. Biomass boilers respond much less rapidly to variations in load. From start-up they can take several hours to get up to the required temperature and pressure. Steam is much more difficult to store than hot water. The boiler will have some in-built thermal storage and the use of steam accumulators provides some flexibility, but the key barrier at many sites is that a biomass steam boiler should be designed for a consistently required base-load.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Fuel gas-fired boiler fuel gas-fired boiler product presentation is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. Oil injected into the furnace, if the gas and air mixture within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a distribution box, it may also be assembled and medium-sized factory. Fuel gas-fired boiler safety valve installation points introduce fuel gas-fired boiler safety valve needs to be installed in the correct installation steps, in order to avoid mistakes, resulting in what needs to pay attention to danger, fuel gas-fired boiler safety valve installed it? Here, I introduce: 1 fuel gas boiler safety valve should prevent the lever means and movement of the self-weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly . 2. Rated to 0.5t h evaporation boiler fuel gas /, at least two safety valves installed; Rated evaporation 0.5t h or less fuel gas boiler /, mounted on at least a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. 3. Fuel gas-fired boiler safety valve to the boiler tubes, cross-sectional area should not be less than the import safety valve cross-sectional area. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of all the exhaust valve. 4. Fuel gas boiler safety valve should be installed vertically in the boiler drum, header high position. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. 6. Fuel gas-fired boiler safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
Gas boiler burner failure how to do? Fault gas burning boiler opportunity arise, the most frequently occurring burner ignition rods gas boiler is not firing. The reason is concerned, it is because the ignition rods gap sandwiched carbon residue, oil phenomenon appeared, followed, that is because ignition rods chipping, moisture or leakage, furthermore, to stick ignition misfire, is because the distance between the ignition does not stick, too long or too short. Gas boiler burner ignition misfire rod, there may occur ignition due to the damage the insulation coating rod, ground short circuit; Then, since the ignition cable is transformer failure, including cable disconnection, connector damage caused by ignition when a short circuit; transformer disconnection or other failure occurs. When it comes to measures to deal with it is, it will include clearing, as well as new ones to adjust their distance, lane changing and changing transformers. Further, when we are faced with the ignition rod on the gas boiler burner spark reasons but misfiring, because the cyclone disc ventilation gap is blocked by carbon deposits, resulting in poor ventilation, or because the oil nozzle is dirty, clogged or is worn, it is because there is relatively small throttle angle setting. Gas boiler ignition spark rod misfiring but also may be due inappropriate firing rod tip from the leading edge of the oil from the nozzle (or protrude too retracted), moreover, the gun is because the first solenoid a valve clogging debris (small kerosene gun); if too viscous oily or not easily flow filtration system or re-clogging of the oil valve is not open, that the pump inlet is insufficient, low oil pressure. Finally, there is a spark ignition rods but misfire, because the pump itself or filter blockage in the oil because of its more water (boiling abnormal noise within the heater). For gas-fired boiler ignition spark stick but misfire, we must first be clear; the next, which is to be cleaned, such as not enough time to pay attention to new ones; furthermore, also is to pay attention to transfer a small test before they can .
