Fast boiler has been to uphold the "mold character, and create boutique" business philosophy, after learning of the status of the state forest mountain elementary school, we are non-stop, quickly prepare a large number of teaching supplies, to the mountains in order to improve children's education hardware conditions positive contribution. In order for children to drink purified water clean and sanitary, after the group discussion after deliberation, determined to provide six sets of water purification equipment and pipeline machine. Teachers and students by means of this device can drink safe water purification, we can say that they know how these "water" next to the Red Flag Canal precious. Watching the children line up smiling face after the contact of water, we all feel distressed bursts.
The reason you need to know the boiler energy consumption (reheat steam temperature) reheat steam temperature problems 1. Circumstances reheat temperature rises 1.1 Move boiler furnace flame center, furnace outlet temperature increases (see main economic indicators No. 5 boiler exhaust gas temperature). 1.2 coal increased too fast. 1.3 Excess air amount is increased. 1.4 pulverizing system start-stop. 1.5 Automatic control of the reheater desuperheating water improper adjustment. 1.6 reheater sootblowing time poor choice. 1.7 feed water temperature is low. 1.8 the high pressure turbine exhaust temperature is high. Next to the 1.9 high leakage, high reheater inlet temperature. Hot and cold extraction section greater then 1.10. 1.11 boiler heating surface design is unreasonable, over-temperature reheater tube wall, forced cooling operation. 2. Reheat the following partial flame temperature is lowered center 2.1: burner tilt deviation, hem; burner is switched from the upper to the lower layer, the lower layer or to an excessive amount of the powder; volatile coal fraction is increased, the pulverized coal thinning, water reduction. 2.2 reheater heating surface fouling, slagging, fouling the interior. 2.3 Save reheat the heated drain valve. 2.4 automatic adjustment inappropriate, excessive reheater desuperheating water. 2.5 feedwater temperature. 2.6 economizer and water wall sootblowing time poor choice. 2.7 reduce the amount of coal too fast. 2.8 # 1, # 2 high pressure heater is disabled, increasing the reheated steam flow.
What is the working principle of horizontal three pass industrial steam boilers, steam boilers, as you know, the main heat source on industrial production, has played an irreplaceable role. Depending on the fuel, coal-fired steam boiler can be divided into steam boilers, biomass steam boiler, gas steam boiler, electric steam boiler, steam boiler fuel and the like. In recent years, our country can be seen from the introduction of environmental management and protection policies, China's degree of attention to the ecological environment. In order to better protect the environment, and to provide people with a better living environment, serious pollution of coal-fired boilers and biomass boilers have been gradually replaced by cleaner and more environmentally friendly gas-fired boiler, the gas boiler has become the mainstream of industrial boiler products. Many users only know enough, I do not know why, small series and everyone works share a gas steam boiler. Today, we talk about the working principle of gas steam boiler, let everyone know more about this type of boiler, that does not hand foot disorder panic purchase. Simply put, gas steam boiler is to achieve chemical energy into heat energy of a carrier. Natural gas, liquefied petroleum gas, fuel gas such as city gas released by combustion heat is transmitted to the water in the boiler, so that the water temperature increases, the output rises to a certain temperature after high-temperature steam, and then fed through the steam pipe production plants, for Production and processing. As this gas steam boiler 4 tons, is provided with a housing inlet, a main steam valve stem, sewage seat, valve stem, the stem and the pressure gauge on the inlet seat economizer, the boiler outlet pipe on the other seat. By interaction over the stem of the gas steam boiler is formed of the following loop: 1, the normal water gas shift cycle: water - softened water tank - the supply pump - the boiler - steam - sub-cylinder - workshop; 2, economizer softening tank water circulation: By circulating pump, an economizer and a water softening tank formed between the reciprocating cycle; 3, the smoke box, economizer condensate normal blowdown boiler water is discharged via the sewage pipe to. Outfall a seat mounted two gas steam boiler drain valve, blowdown, requires two discharge valves are sequentially opened, the sewage.
In Malaysia, there are lots of biomass fuel like palm shell and palm fiber, we recommend SZL or DHL type for using water tube boiler. If the steam capacity is less than 25t/h, the SZL will be the best choice, whereas if the steam capacity is more than 25t/h and less than 100t/h, DHL corner tube boiler could be chosen. In addition, the gas or diesel is another kind of source for the local user, so SZS type could be recommended.
