Heating stove heating stove manufacturers to introduce the flue gas side of the steam temperature regulating stove manufacturers to introduce the flue gas side of the heating boiler metal temperature simulation steam temperature adjustment: adjusting the flue gas side, by changing the radiation and convection heating surface in the boiler is the heating surface the method of heat absorption or distribution ratio change amount of flue gas flowing through the superheater methods to achieve steam temperature regulation, and is mainly used to adjust the reheat steam temperature. Principle steam temperature flue gas damper adjusting means is changed by the shutter reheater flue gas flow through the regulator to achieve the reheat steam temperature.
The cost of chemical gas steam boiler metal temperature simulation how much money one ton cost of gas chemical plant steam boiler how much money one ton? For various manufacturers during boiler operation is required in the calculation of the running cost. Relatively late this business relationship between the process of production of inputs and outputs. How much is the cost of gas for steam boilers one ton This mainly involves two computing data. One is the relationship between the price of purchase boiler body, there is a cost price of gas steam boiler in the late running. In this regard, technical staff fast Boiler For these analyzes, the chemical analysis of the current use of a gas steam boiler 1 t is possible, that the cost of chemical pre-purchase boiler at around 120,000. Can only be calculated at a specific cost data for the operation of the boiler, the boiler one day assuming 8 hours per hour air consumption at 70-80 cubic meters. At the same time every day plus the cost of labor, accounting can simply run out of basic price. At the same time, both will be able to obtain data aggregated cost of chemical gas steam boiler how much money a ton.
Pay attention to gas steam boiler metal temperature simulation which runs: customer after purchasing gas steam boiler, not sit back and relax, but also need to seriously understand the operation of the boiler starts, the attention to what matters, so you can be more effective in ensuring the long life of the boiler. 1, the cold gas steam boiler working pressure from the ignition rises, boost heating time is about 3 to 4 hours. When the boiler pressure rose to 0.05 ~ 0.1MPa, should wash boiler pressure gauge and water level gauge; when the boiler pressure rose to 0.15 ~ 0.2MPa, the boiler should be shut down air valve and check valve for leaks, measures should be taken if a leak be eliminated; when the boiler pressure rose to 0.2 ~ 0.25MPa, boiler blowdown to conduct a test, when sewage boiler water level should be above the normal water level, and check the drain valve leaks, if the leak should take measures to eliminate; when the boiler when the pressure is raised 0.3MPa, a full review of the fastening member boiler pressure element, such as manholes, hand bolt holes, and check holes of each flange connection is loose, and a tighten heat. 2, the pump checks whether the automatic operation to maintain the normal water level, water level in the "line from the pump" the normal start, the water level in the "stop pump line" pump can be stopped; 3, control pressure is normal, when the steam pressure reaches when the set value, the combustion is stopped, lights overpressure, the pressure is reduced to the set value, the boiler can start automatically; 4, when the load pressure reaches the set value, the fire load due to a small fire, when the pressure drops to set when the predetermined value, the transfer of small fires burning fire; 5, when the pressure can not be set at normal pressure shutdown, the shutdown will alarm the second overpressure shall be restarted; 6, the exhaust gas temperature should not exceed 300 ℃, otherwise, the shutdown should check; 7, when gas steam boiler into normal operation phase, boiler fireman personnel to strengthen the boiler, instrumentation and safety accessories and auxiliary equipment is a monitor, a good job is a boiler and auxiliary equipment inspection tour and in a timely manner fill run record.
Recently, Xuzhou City ushered in the good weather blue sky, sweetness and light, a set of numbers from the Xuzhou municipal environmental protection department made us confident to bring back the blue sky. According to the latest air quality in the province informed that this year, two good days in Xuzhou City 73 days, an increase over last year eight days; PM2.5 concentration of 78μg / m³, the concentration of upward momentum have been effectively curbed. The atmosphere improving governance has achieved victory.
Since April this year, Xuzhou municipal government set up the city's Operations Command prevention tackling air pollution, and the establishment of 16 specialized working groups in accordance with the classification of remediation tasks, the relevant departments to deploy officers to concentrate on work, concentrate on promoting the prevention and control of air pollution crucial action. At the same time, Xuzhou developed and issued in the history of the most aggressive, the most comprehensive measure of the "Xuzhou City in 2018 tackling air pollution control program," the task of governance engineering, project oriented, technology node.
First, action aimed at the city's 13,654 "messy dirty" business, and sort of closure to ban or stop crime measures. "Coal-burning pollution" key problem is the political commissar of the governance of Xuzhou City, after the operation began, to more than 10 tons of steam coal-fired boilers implementation of classification regulation, the city's 18 coal-fired thermal power companies implement flue gas treatment project off white, investigate and shut down downtown bulk coal processing operations point 171, for 22 coal-fired power companies and the city's 11 coal production (including coal washing) enterprises in high frequency sampling.
Furniture, printing and dyeing, filling stations and other industries, focusing on pollution VOCs special inspection work, check the company focused on source control, process management, end of treatment, the treatment facilities to ensure the normal operation of equipment, environmental protection do not have the processing power of enterprise firm shall be eliminated by shutting down.
