Szl Series Industrial Coal Fired Hot Water Boiler

Gas and coal-fired steam boiler steam boiler compare what are the advantages of (1) from the traditional economic point of view and our energy structure, coal-fired boilers due to the low one-time investment costs of popular people favored, especially in the rich coal resources , green area less demanding 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 coal-fired boiler pollution: waste, emissions, waste water, "three wastes" and taste, governance Yijiao difficult (especially desulfurization, coal-fired boiler desulfurization technology currently has achieved some results, but the high investment costs, complex operation, covers an area of large), from the social perspective should limit the use of coal-fired boilers. Soot emissions (2) oil-fired boilers, although lower, but its emissions of harmful NOX, SOX gases are causing "photochemical smog" and acid rain culprit, you want to be like governance as coal-fired boiler soot emissions control. (3) gas boiler has 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. (4) not only set in three furnaces comparison, gas boiler lower costs and operating costs, 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.

Steam boiler buying guide and cautions because the steam boiler 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.

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.

Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon szl series industrial coal fired hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
