Coal-fired automatic coal hot water dzl boilers to gas-fired boiler and the basic requirements of a program, the transformation of the basic requirements: 1, the boiler must be carried out in accordance with "Steam Boiler Safety Technology Supervision" and "Hot Water Boiler Safety Technology Supervision" and relevant national technical regulations, construction program should be sent to the local technical supervision departments for approval. 2, to determine the value in use based on the transformation of the boiler has the age and state of the art, taking into account the life expectancy of the boiler. If the boiler use a longer useful life, and the pressure there is a serious corrosion, scaling and overheating phenomena such elements, no transformation of value. 3, boiler walls, chimneys, water supply and air supply, the wind system should remain largely intact. 4, after the transformation of the original technical parameters should be kept constant boiler (operating pressure, temperature, etc.) or the load and to improve the efficiency of the original boiler. 5, after the boiler should comply with national environmental and technical indicators, solve the problem of smoke and dust, meet environmental requirements. 6, when the boiler should try not to change the original pot, and the body is pressed by the original system architecture, covers the smaller the better. 7, rehabilitation programs should be simple, low investment, short construction period and quick, safe and reliable. Second, the transformation method: 1, removal of the original coal-fired boiler slag machine, equipment on coal, dust, chain grate and gearbox. 2, according to the diameter and length of the flame, furnace installation height determining geometric dimensions and the burner. 3, making the furnace, the furnace bottom refractory brick, a semicircular shape. 4, the front arch openings mounted burner nozzle. 5, after that the flame away from the center position of the tube the arch, the arch of the pipe on the basis of the original slope, heightening baffle wall, the protective tube arch. 6, install blast doors. 7, install the induced draft fan drive. 8, the body of the boiler water test pressure 1.5 times the working pressure. 9, the automatic control system installed. Third, the technical proposal: 1, furnace design should consider the flame length and diameter of the flame of the combustion gas, so that the furnace space is filled with the best of the flame, the flame not Wall flush. 2, as the main component of natural gas CH4, H20 generated after combustion, steam share large, so that strong radiation, heating furnace suitably increased to take advantage of the radiation heat transfer, thermal efficiency, reduce the consumption of steel, ensure that the boiler output, and may increase the boiler output. 3, a slight positive pressure within the boiler furnace using a combustion or slightly negative pressure, the sealing performance of the boiler furnace walls to strengthen, not air leakage. 4, due to the smaller excess air ratio of the gas boiler, combustion requires less air flow, coupled with the removal of dust, dust and small flue system, the flue resistance is reduced, a large surplus primer fan flow, using file when the damper plate adjusting the power loss is large, frequency control can be induced draft fan air volume regulation. 5, after the furnace door and see the fire smoke chamber above the chimney, mounted two proof doors, in order to improve the antiknock performance of the boiler. 6, the boiler flue gas the volume of gas in the vapor component is generally 15% to 19%, well above the coal-fired boiler flue gases generated in the water vapor content of 6% by volume or less. Boiler shutdown and startup, due to the low wall temperature of the boiler heating element, when less than less 50 ℃, the flue gas water vapor dew condensation on the wall will, if not removed condensate with the condensate of the contact wall would be C02 acid gas corrosion of furnace wall and the insulation material due to water absorption and thermal insulation effect will be lost. Therefore, before and after the gas hot water boiler smoke box and the rear box and the rear flue smoke condensate discharge means to be provided, promptly boiler condensate removal. 7, the gas boiler-system control function should have combustion process. Pre-blowing may be implemented, auto-ignition, flame detector self-test, automatic load adjustment, flame monitoring, fault alarm interlock shutdown, the gas leak detection valve, induced draft fan and burner control sequential chain protection. 8, in order to prevent fluctuations in the gas pressure regulator to meet the burner requirements, the installation of a gas regulator metering panel outer gas inlet in the boiler room, the surge counter can be accomplished by filtration, regulating, metering, safety shut-off functions.
