Gas-fired steam boiler coal fired supplier principle gas steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and which is vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source. Boiler and boiler shell consists of two main furnace and ensure accessories, ancillary equipment instrumentation, control and protection system safe and economic operation of its continuous constituted. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. The basic components of a steam boiler and a steam boiler operating principle is constituted by a series of devices can be roughly divided into two main parts and auxiliary equipment. The main components of the boiler are: 1. Furnace: fuel burn-up and ensures that the boiler outlet gas temperature to a value of convection heating surface cooled safe work; 2, economizer: utilizing the heat of the flue boiler feedwater heating, to reduce the exhaust gas temperature, fuel economy and functions. 3, the drum: the respective heating surface and joined together and the boiler water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 4, water wall: mainly radiation heating surface of the boiler, the absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 5, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion; 6, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reduced exhaust tobacco temperature, increase boiler efficiency. 7, the furnace walls: a housing to protect the boiler, since sealing and insulation. Heavy furnace wall of the small boiler may also function as a support member boiler. 8, the frame: a support member and the fixing boilers, Purple east 15:33:06 boiler auxiliary equipment are: 1, the wind equipment: induced draft fan and chimney via the flue gas generated in boiler operation sent to the atmosphere. 2, dust removal equipment: removing fly ash in the boiler flue gas. 3, the fuel supply equipment: fuel storage and transportation functions. 4, water supply equipment: water pump water supply through the water into the boiler by the processing device to. 5. Dust Cleaner equipment: removing ash from the boiler and carried away. 6, the blower device: by the air blower after exports the furnace air preheater and a coal grinding device heating applications. 7, the automatic control device: automatic detection, process control, automatic protection and automatic adjustment. IMPORTANT boiler maintenance and a maintenance, water maintenance method 1. The boiler must be a qualified treatment, which is to extend the life of the boiler, ensure the safe operation of the gas and steam. 2. The water temperature should be close to the furnace temperature, preferably above 20 ℃. 3. The need for low-water cutoff periodically inspect maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4. require periodic blowdown operation, daily (per shift) at least once, after the sewage drain valve should be checked whether the influence by dirt and leaks; if it must be excluded. 5. Shutdown the steam pressure is not maintained, the boiler will produce steam space negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened. 6. smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.
Steam boiler buying guide and cautions because the steam boiler coal fired supplier is an extremely easy to use and very clean and environmentally friendly boiler, so it is widely used in various fields, and very loved by the people. We buy when the steam boiler, it must first be checked in detail, to see its various parts is normal, and make sure it's good quality. From the perspective of traditional economic and energy structure of China's point of view, gas boilers due to the low one-time investment costs of popular people favored, especially in the rich coal resources, environmental protection and less demanding areas people prefer to select it. But in resource-poor coal, coal prices are not low areas of oil, gas and coal compared to a certain competitiveness. Another reason people like coal stove is easy to operate. But gas-fired boiler pollution: waste, emissions, waste water, "three wastes" and taste, governance Yijiao difficult (especially desulfurization, the current gas boiler desulfurization technology has made some achievements, but the high investment costs, operation complex, large area) from a social perspective should limit the use of gas-fired boilers. Gas boilers efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no need to transport fuel, no need to deal with soot, due to natural gas combustion no impurities, no corrosion damage to boilers and related accessories, boiler long life , defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Many have been using coal as the heat source of industrial companies now use gas stoves geographical mandatory requirements, it may be gas steam boiler threshold will be higher in the future to strengthen environmental protection efforts. Soot emissions from oil-fired boiler, although lower, but its emissions of harmful NOX, SOX gases are causing "photochemical smog" and acid rain culprit, to be governance as soot emissions as gas boiler control. Gas boiler with a small footprint, less pollution emissions advantages, but also the cost of the boiler room is not set up, the use of natural gas fuel prices, operating costs lower than oil-fired boiler. By comparison of three of the furnace, gas boiler not only set a lower cost and operating cost, and its social benefits are incomparable. Natural gas is the cleanest fuel, is the least polluting fuel emissions, gas-fired boilers will be the development trend of boiler final.
Low nitrogen boiler revolution to lead the industry in fact so much importance to the APEC summit in nitrogen oxide emissions from the boiler is not accidental. Nitrogen oxide emissions into the atmosphere dissolved in water will generate nitric acid rain, caused extensive harm to the environment, causing huge losses to the economy. For the boiler, fuel combustion is the main part of the nitrogen oxides generated. However, in most cities, nitrogen oxide emissions from the boiler still remain at a high level, or simply just to reach deeper coal to gas demand, low nitrogen, low dust and other environmental requirements far not on the agenda.
Coal to natural gas operations bunch of factors that vertical pressure steam boiler coal fired supplier energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.Free Chat
