The main functional difference component of natural gas and 1 ton steam boiler applied in paper mill 1. The raw materials of the boiler combustion products of coal are carbon, hydrogen, oxygen, nitrogen, sulfur and water. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fee gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. in addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. After combustion, sulfur dioxide, sulfur trioxide and nitrogen oxides are discharged to the atmosphere, environmental pollution, cause harm to humans. The main component of natural gas is CH4, CO2 and H2O mainly produce post-combustion, compared with coal-fired boiler, gas boiler emissions of more environmentally friendly and better able to reduce urban air pollution problems. 2. The most common combustion coal-fired boilers are stratified combustion. This process mainly refers to coal fuel disposed in a larger work surface to complete combustion. Passage means to the coal bunker broken belt, ran into the furnace through the coal feeder, coal use wind; primary embodiment using a gas boiler furnace combustion gas into the main combustion chamber, combustion is completed in the form of flare. Wherein the main advantage of the stream bed combustion mode is reliable and stable, good economy; coal corresponding disadvantage is the need, not flexible. At the same time, the combustion mode is the stratified combustion "firing-sided" and "staged combustion", which is in Rongyifasheng bunker coal bunker bridges. Combustion chamber combustion with high efficiency, clean environment, burning the advantages of automation. At the same time, such a small area of ​​combustion, combustion does not need to be transported, and the combustion gas free of impurities, which boiler life relatively long. Gas boiler can withstand a high thermal load, it is possible to select a smaller furnace space. 3. coal-fired boiler safety relatively safe, small furnace combustion hazard. To be clear Anquancuoshi gas boiler, Rongyifasheng explosion within the explosion limits. The main use of coal-fired boiler stratified combustion, therefore, the need for timely when coal-fired boiler shutdown, even if you stop coal, there is still a lot of fuel in the furnace is not, can continue to burn. Accordingly, the gas pressure rising in the furnace, endanger the safety of the vessel. The main gas-fired boiler using natural gas fuel. When the boiler needs to be stopped in time to run, you can understand, stop the transmission, security is guaranteed. Further, no storage device can effectively reduce transportation costs, space costs. But the most important thing is explosive natural gas to reach the explosive limit, once the fire may occur, endangering the lives and safety of the explosion, while coal-fired boilers do not need to take this into account. 4. vented combustion coal-fired boiler with the blower is run together. Coal is a coal-fired boiler with solid fuel. The particle size of coal and coal combustion own characteristics resulting in a large excess of gas in the furnace during combustion of coal-fired boilers. Further, in addition to leakage of the combustion chamber flue, the coefficient of excess gas can reach 2.0 to 2.4. The main ventilation gas boiler is a slight positive pressure ventilation structure having an internal combustion, the combustion products in combustion operation is mainly discharged from the blower. Boiler primary combustion gas may be a hydrocarbon such as methane gas mixed with air, in which operation of the ventilation exhaust port air ratio only 1.2≤1.3 ~ 1.05, the amount of smoke produced by the boiler is very small, the gas less impurities, while the flue gas emissions are also easier to meet the requirements of national combustion equipment, slag and other dust without increasing the equipment. Gas boiler can not only reduce environmental pollution, and the relatively small investment in equipment, boilers longer life expectancy.

At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the 1 ton steam boiler applied in paper mill used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.

Gas boiler precautions required during installation methods, or steps :( a) a foundation base of the boiler should be provided is determined according to the local soil, manufacturers design reference by the civil sector again. After reaching the base strength boiler, the boiler should drawings inspection and acceptance, and to draw the whole boiler three reference lines: a, longitudinal reference line - drum center or the center of the combustion apparatus. b, lateral reference line - the center of the front axle or chain grate slag centerline of the machine. C, elevation reference line - can be selected from a number of locations about four weeks, respectively, on the basis of the marking, the relative offset between the markers should not exceed 1mm. Furnace in place. After assembly the lower part of the boiler in place first, then the upper assembly large, the upper and lower portions need to find a combination of two positive pads firmly, should be both inside and outside the two casting. Installation location and size deviation test methods according to GB50273 "boiler installation engineering construction and acceptance" implementation. (B) lifting the boiler, during lifting, should be suspended on a lifting lug drum boiler ready large, the boiler on a foundation base coincides with the pre-drawn reference line. The longitudinal centerline of the boiler and the foundation, the deviation is not more than 3 mm, and the inclination with the center line of the drum hammer correction, allowing the central drum inclination is not larger than 5 mm, otherwise use horns foundation base and the junction pad level. Maximum level (c) Installation of boiler network (1), water supply conduit installation requirements typically require as backup pool below the normal water level line of the boiler, so as not to shutdown, boiler feedwater flowing into a large number of drainage caused to start the next . At the outlet of the tank (i.e., an inlet feed line) should be installed wire screen. (2), a main steam line installation requires the main steam lead pipe straight run section should be more than 0.5 m, the bending radius should be 4-5 times the diameter of the pipe, the trap should be fitted at the lowest line in order to prevent water hammer pipe, while to be reliable insulation. (3), the safety valve should be installed in the valve installation requirements after the hydrostatic test, the safety valve shall be fitted exhaust pipe, the exhaust pipe of the safety guide outside the boiler house, allowed valving the exhaust pipe. (4), mounting a lower water table level table downcomer must access a safe place, Hancock rotating flexible water table, not leaking, water table must be installed to the lighting device, easy to observe. (5), a pressure gauge mounting means so that when the scale gauge vertical plates, should be painted red gauge scale to show the maximum allowable pressure boiler, rotating flexible plug gauge, not leaking, water flow, pressure gauges insulation prohibited. (Iv) the boiler chimney installation requirements, when lifting the chimney, the chimney should be straight, horizontal direction lead length should not be too long, generally less than 5 meters, the height of the chimney should comply with relevant national standards. To add chimney rain cap, the weight of the chimney should not fall directly on the boiler chimney take over the host. Installation (e) combustion system: 1, according to the combustion system of FIG power line control circuit, a control signal line and the control line is electrically connected, the program should be installed reliable ignition and flame failure protection devices. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine.
