The fast boiler related personnel monitoring center, started after the boiler, the boiler pressure, exhaust gas temperature and other sensors will automatically collecting various kinds of boiler operation data and real-time transmission through the mobile network to a remote monitoring center located at the headquarters of the fast boiler ; operating data once abnormal or deviation, the monitoring center monitoring personnel can detect and organize experts to analyze and issue alerts and corrective measures.

Coal-fired 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.

Fuel gas control step and the blowing process air volume of the total fuel gas oil steam boiler efficiency chart steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.

Pressure boilers Products of the non-pressure hot water boiler, also called pressure boilers, boiler usually refers to the top does not bear the water column static pressure of the heating system. That is quite an open hot water tank. Meaning pressure boiler: boiler body opening to the atmosphere. In any conditions, the boiler at the water line are zero gauge pressure boiler. Pressure boilers Model consists of three parts, connected by a hyphen between the parts. Categories: pressure hot water boiler is mainly classified by fuel can be divided into CLDR (CWDR) often piezoelectric hot water boiler, CLHS-YQ (CWNS-YQ) pressure fuel (gas) hot water boilers, pressure coal-fired hot water boilers.
