Recently, the Government Office of Hebei Province issued the "Hebei province coal investment projects coal alternative management approach", mainly to strengthen air pollution control, the implementation of total coal consumption control target. The new "management approach" referred to new construction, renovation, expansion project of coal, coal should carry out the same amount of reduction or substitution (hereinafter referred to as a substitute for coal). Coal substitute coal should be completed before the project goes into operation.
These measures apply to administrative areas in Hebei coal for direct consumption of fixed asset investment projects. It refers to the direct consumption of coal raw coal, washed coal, other coal washing, coal slurry, coal, coal and other raw materials or fuels production and processing or combustion, its coal facilities (facilities, tools) including boilers, furnaces , gasification, blast furnace and so on.
Coal alternative pathway includes the following four aspects: the elimination of backward production capacity, excess capacity and Yajian enterprises closed down, converting reduce coal consumption; the implementation of central heating, reduce coal consumption saving technological transformation or removal of equipment out of coal-fired boilers and other equipment coal consumption; use of renewable energy, natural gas, electricity and other clean energy alternative to coal consumption; the other to meet the requirements of coal consumption reduction approach. Replacement of coal coal project supervision and management, energy conservation authorities responsible for co-ordination at all levels.
Eliminating the problem of pressure test: GB150-1998 "Steel Pressure Vessel" Article 3.9 states: "to not make container pressure testing in accordance with the provisions of 3.8, the design unit should put forward measures to ensure the safe operation of the vessel, and note on drawings Ming "There are many standard deviations the user's understanding of this provision, is summarized in the need to clarify the following two questions: First, under what circumstances can relieve stress test? Second, the measures may be required after relieve the pressure test? When the catalytic cracking unit with a regenerator and a large reactor and the heat insulating layer can not withstand those based hydraulic test: in fact, only relieve pressure test performed Spot welding large pressure vessels for pressure testing the impossible, such as water by weight of the pressure vessel and the like. In other words, the reason why the pressure test exemption, because they do not have the container or a pressure test, or simply not pressure tested. In short, rather than eliminating means you can not do not do it, it is not without basis as a general pressure test in the factory production of pressure vessels. It should be noted that the pressure here means a pressure test test.
Steam boiler heat loss is what causes? Steam boiler heat loss caused to the user a lot of burden, whether it is hot steam boiler what is causing the loss of it? To analyze together with you today. Specific causes heat loss of the steam boiler at several: 1: heat loss of exhaust energy: smoke exhaust gas boiler comprises means losses are not completely absorbed by the steam heat loss. How caused? Short distance high temperature flue gas fan suction force is too high, the high temperature flue gas immediately excluded from the boiler; a small heating area, high temperature flue gas boiler can not be sufficiently absorbed. 2: the fuel gas does not completely heat loss: the combustible gas discharged from the flue gas generated in a boiler, the fuel in the combustible gas or gaseous fuel combustion process itself does not contain all of the incomplete combustion releases heat losses arising. As the incomplete combustion of carbon monoxide and carbon dioxide containing off-gas produced by combustion compared to the complete, only a quarter of the amount of heat released. 3: Solid incomplete combustion heat loss: refers to the solid fuel combustion process as a fuel grate down the drain does not release the heat of the flammable substance and ash contained in the combustion of the fuel can not completely burned released heat loss caused. 4: Loss steam boiler Grate: refers to the internal heat loss of the absorbent. 5: high temperature heat loss: Indicates high water temperature and hot water temperature, heat loss. 6: heat losses within the new design steam generator with good price tube due to furring bilingual.
The hotel's hot water boiler purchase Notes: The hotel is one of the main users of the use of hot water boiler, hot water boiler output of hot water can provide a warm heating, hot water bathing and other purposes for visitors. The face of many brands and types of boilers, which one is best for your hotel to use it? Optional hot water boiler needs to pay attention to what matters it? Fast boiler Xiao Bian to share ideas with you! First we buy hot water boiler, water needs to consider the hotels. 1, the total number of hotel rooms need to use hot water. 2, with or without heat recovery may be (air compressor, generator, etc.). 3, boiler installation space (length, width, height, orientation, surrounding buildings).
