What types of boilers are currently furnace use? Furnace is a boiler shell type specific pressure member. Internal combustion furnace is, outside the boiler water, under external pressure. Therefore, it is the worst working conditions the pressure receiving member in the boiler shell type, one of the most easily damaged component. Due to the high temperature furnace combustion flame, which is higher than the temperature of the boiler shell, its thermal expansion problems in particular. Especially oil-fired boiler, the combustion temperature due to the high oil, high furnace thermal strength, severe temperature changes, it requires the furnace to have a good thermal expansion properties. Currently there are in the form of a flat furnace of cylindrical shape, with a straight cylindrical reinforcing ring, corrugated and the like.

Liupanshui former gas trade assurance supplier 2 ton steam boiler installation to handle documents installed gas steam boiler, should write "boiler installation started application form", and was carrying no less than the following materials to the gas boiler steam boiler for all earthly authority for examination and approval procedures for installation, approval after the order for construction: ① gas steam boiler installed original license; ② gas steam boiler installation boiler installation boiler room started the application form and engineering solutions; ③ gas steam boiler factory technical information; ④ steam boiler room floor plan and steam boiler room design information; ⑤ practitioner certificate installation companies involved in the job of workers. Former gas steam boiler installation, and installation company should also carry complete the ratification of the "boiler installation started application form" to the quality control unit for all territories gas steam boiler and pressure vessel inspection unit signed "Boiler Installation Quality Supervision, Inspection engagement letter" by the test unit values ​​for gas steam boiler installation requirements of supervision.

Gas heating boiler installation steps for the overall operation of the process gas heating boiler is concerned, except as selection, cost analysis, these areas require particular attention, the installation of gas heating boiler is also particularly important aspect, the following small series with you a quick look at the steps to install gas heating boiler. (1) Before the boiler installation should advance to the installation site investigation, because the boiler operation is related to the operating conditions required, therefore, to the boiler installation the actual situation of the site, including the installation location, installation environment, fuel supply and other detailed understanding it also indicates that we, when you want a new boiler, necessary arrangements may require boiler manufacturers professional people, the venue of the boiler detailed study to develop a detailed feasibility analysis, develop a reasonable program of boilers, achieve operating cost rationalized, stable operating conditions, enhancing safety. (2) the installation of the equipment in accordance with the provisions of checks, if they are not in line with the contract, as well as the phenomenon of damage and the like, and timely report and take appropriate remedial measures, which, during the course of the acceptance of particular attention. (3) in the gas heating boiler installation, pay attention to the construction period, the actual situation of the division of responsibilities installation point, install every component and other scientific caution, regulation accordance with laws and contracts. (4) after installation to conduct acceptance tests, the boiler can ensure safe operation, after boiler installation in line with relevant laws and regulations, side to acceptance criteria. In summary, the detailed steps to install the boiler, may be much more than that, but generally the process are indispensable in the process of installation, must be scientific caution, so as not to cause unnecessary trouble to the latter, affect the overall process.

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.
