coal for hot water boiler for sale banda aceh
Second, the clear purpose boiler "coal to gas"
1, while maintaining the original nominal parameters of the boiler (e.g., steam temperature, steam pressure, water temperature, etc.) remain unchanged, maintaining or improving output and efficiency of the boiler.
In recent years, as people's growing awareness of environmental protection, the State also intended to promulgate stringent emission standards for nitrogen oxides. This boiler companies made a mandatory requirement - how to effectively reduce nitrogen oxide content in the boiler flue gas. Therefore, a focus on emissions of nitrogen oxides environmental revolution is quietly boiler industry. But for domestic boilers companies this road is not good to go, because the difficulty of controlling nitrogen oxides and more demanding of the boiler, every 1 mg / cubic meter of emissions control will cause the boiler costs dramatically.
Gas boiler ignition failure divided into several categories? How to deal with? With the advance of coal to gas, gas boilers have been gradually replaced by coal-fired boiler, with a high market share. But gas boiler often encounter some problems, mainly gas-fired boilers can not be said today about the firing of several reasons. 1, a boiler ignition pressure is too high or too low, the range of no ignition. Solution: Check boiler pressure, to see whether the pressure within the pressure range of the ignition of the burner, can be operated in a control cabinet. 2, the boiler water level is too low, ultra-low water level below the boilers, automatic interlocking, burner misfire. Solution: Check the boiler water level is below the low water levels if the boiler. 3, the exhaust gas temperature is too high, automatic chain protection boiler, burner does not ignite. Solution: Check the boiler flue gas temperature, smoke to see if the shutdown temperature is higher than the boiler 4, the gas inlet pressure is too low or too high, the burner is not firing. Solution: Check the burner inlet gauge to see whether the pressure composite ignition pressure boiler 5, natural gas leaks, burner does not ignite. Processing Method: General burner comes with leak detection means may be self-monitoring. 6, a gas burner commissioning and unreasonable air distribution control, auto-off after burner ignition. Processing method: the ratio of gas and air not debugging, the inlet air is too large, the firing automatic fire 7, the boiler emergency stop switch is erroneous, misfire burner (boiler is not in operation) Processing Method: General this time all the features are not method used, can be self-monitoring. 8, own fault burner, burner ignition contact rod iron, programmer failure, warning lights flashing. Approach: this time do not operate their own troubleshooting, and quickly find the right service door.
Tail gas boiler heating surface, promote energy conservation, steam boiler, make full use of surplus gas, iron and steel ring can be part of the No. 2 boiler recently implemented gas utilization upgrading the premise of low temperature corrosion does not occur. The transformation of the original two No. 2 Power Station Boiler 220 t / h circulating fluidized bed boiler, the transformation of 200 tons / hour gas-fired boiler. To reduce the cost, Shaoguan Iron & Steel ring portion can be modified in the original boiler equipment, removal coal system, discharging systems, dust removal systems, fuel systems; Lee used equipment including the original boiler water wall, drum, steel frame, platform escalators, tail shaft convection heating surface, steam systems, water systems and some electrical, instrumentation and other facilities, while adding the blast furnace, a coke oven gas in each system, the new blast furnace, coke oven gas mixing burner 4, the combustion of blast furnace gas device 4, a low-low pressure economizer, the boiler flue gas boiler guaranteed emissions compliance and four 10 kV high-pressure fan, part of the electrical and gas drainage, tail heating surface is not provided at a low temperature corrosion occurs meter facilities. No. 2 boiler after the upgrade, to ensure the boiler flue gas emissions standards and low temperature corrosion tail heating surface does not occur under the premise, as far as possible be able to mix more burning oven gas, surplus gas consumption, save energy and reduce environmental pollution.
