4t Natural Gas steam boiler Agent Nepal

Hot water boiler is one of the important equipment for the district to provide our real estate company, and two gas hot water provide the fast boiler boiler flotilla of environmental performance, in full compliance with state regulations after smoke was detected in the rear of the boiler. And boiler operation is safe, stable, we use the very at ease. --customer feedback

You know how the boiler works? Boiler parameters is a main boiler performance indicators, including the boiler capacity, steam pressure, steam temperature, water temperature and the like. Boiler capacity available rated maximum continuous evaporation or evaporation is represented. Rated evaporation under a predetermined outlet pressure, temperature and efficiency, the amount of steam per unit time of continuous production. Maximum continuous evaporation under a predetermined outlet pressure, temperature, per unit time the maximum continuous amount of steam produced. Steam pressure and temperature parameters including 4t steam boiler agent nepal, generally refers to a superheater, superheated steam pressure and temperature at the outlet of the reheater and superheater if no reheater, saturated steam pressure and temperature at the outlet of the boiler refers. Refers to a water temperature of the economizer inlet temperature, inlet temperature refers drum without economizer. Boilers can be categorized in different ways. Boiler use can be divided industrial boilers, utility boilers, marine boilers and boiler locomotive; by the boiler outlet pressure can be divided into low, medium, high pressure, high pressure, sub-critical pressure, the supercritical pressure boiler; boiler and by water flue gas flow path can be divided into the fire tube boilers, fire tube boilers and water-tube boilers, fire tube boilers and wherein the fire tube boiler and collectively shell boiler; press cycle can be divided into natural circulation boiler, auxiliary boiler cycle (i.e., forced-circulation boilers), and the combined circulation boiler once-through boiler; by combustion, the boiler chamber into the burner, and boiling Stoker furnace. Water vapor system, feedwater heated to a temperature in the heater, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the water wall downcomer inlet header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam from the superheater to the upper stream drum, continue to become superheated steam endothermic certain temperature (most of the current 300MW, 600MW unit main steam temperature is about 540 ℃), and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere.

Laundry hotel special reference to the current selection of 4t steam boiler agent nepals Hotels generally use the hot water boiler for heating and sanitary hot water, kitchen utensils gas can be directly used, but still need to supply steam laundry room, laundry room steam supply pressure to be 0.4-0.6 MPa, generally an amount of steam in the hotel laundry 0.5 ~ 2.0T / H, steam day with about 3 to 10 tons. Under the premise of the city's coal-fired boilers can not be used, the choice of energy sources natural gas, diesel, liquefied petroleum gas, electricity, in what exactly it is more appropriate? First use to compare the cost of various energy sources, according to Henan hotel energy prices, natural gas is 3.0 yuan / Nm3, diesel 9.0 yuan / kg, liquefied petroleum gas 15 yuan / Nm3, the price of 1 yuan / kwh. Compare 1 ton of steam produced by a variety of energy costs as follows: Energy Category Energy calorific value of natural gas in energy costs per ton of steam 8600kcal / Nm380m33.0 yuan / Nm3240 yuan / ton diesel 10400kcal / kg66kg9 energy consumption per ton of steam energy prices. 0 yuan / kg594 yuan / ton liquefied 22000kcal / Nm331m315 yuan / Nm3465 yuan / ton electric 1kwh700kwh1 yuan / kwh700 yuan / ton Note: energy consumption efficiency estimated by conventional steam boiler; Nm3 refers to the standard state volume of gas M3; calculated from the above analysis, the use of natural gas per ton of steam lowest cost, most economical operation, electrically heated steam up costs. Gas steam boiler typically 2 to 3 sets of selection, single nominal amount of evaporation 0.5T / H ~ 1.5T / H. Gas-fired steam boiler boiler range belong to the state regulators, the need to build a separate boiler room, not like pressure hot water boiler as the main building or in the basement, while the city hotels are often difficult to have a location to build a separate boiler room. In recent years, there is a new type of gas steam boiler, the water capacity is small (less than 30L), a single evaporation accessible 1T / H, do not belong to the state boiler steam boiler regulation range, can be in the basement, a good solution to the conventional steam boiler no suitable location problems.

There are build on the control of emissions of nitrogen oxides boiler in order to achieve NOx emissions from combustion boilers of less than 30mg / m3, reached the world advanced level. Austrian far low nitrogen fuel gas boiler Staged Combustion Process of the invention into three regions in the furnace combustion techniques, primary combustion zone into the small portion of the fuel, the fuel required for the combustion air into the furnace in stages, the air volume of 80% left and right into the main combustion zone, the primary combustion zone of the upper (downstream of the flame) of the fuel injected into the secondary combustion and the formation of Carrying out a reducing atmosphere in the third zone into the combustion air required Further, complete burnout process. To create a discharge for the control of nitrogen oxides boiler fuel and air in order to achieve staged combustion gas boilers achieve emission limits is very basic configuration of environmental protection facilities, comprising an electrostatic precipitator or bag filter, gas boiler efficient desulfurization apparatus, a selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) and the like denitration apparatus. All aspects of air pollution sources to install automatic monitoring facilities, 4t steam boiler agent nepals and networking with the environmental protection department, install a distributed control system (DCS system), real-time monitoring of gas boiler pollutant emissions. All-premixed combustion technology implementation of a number of Austrian far improved combustion technology after years of build have on the control of emissions of nitrogen oxides boiler fuel and air in order to achieve staged combustion. This technique can be gas boiler NOx emissions chain by 70% -60%. At present, to solve pollution problems of small and medium industrial gas boilers have four energy saving way. First, clean fuels covered by the remaining gas boilers, boiler premix combustion technology implementation of a number of improved combustion technology after years of Austrian far as natural gas boilers, biomass boilers and so on; Second, the rising water boiler technology.
