Low Price 1t Natural Gas steam boiler Thailand

Commissioning of Boiler gas boiler commissioning must be carried out after the hydrostatic test. Before commissioning, should be a comprehensive inspection of each furnace parts, electronic control devices, wiring, etc. are normal, water supply, oil furnace if opened, electrical contacts are in the set position. 1, depending on the size of the fuel consumption, the initial damper, the hydraulic pressure. 2, the power is turned on, the power switch to open the cabinet, the water pump starts furnace, (if the pump is rotated into the anhydrous, pump purge valve is opened, the air exhaust pump). 3, control checks whether the normal water level electrode. 4, check the burner operation is normal. Starter burner starts combustion when the water level rose to a predetermined level, the start of combustion is normal to observe: Start no vibration noise, stable combustion, no smoke, orange yellow flame, burning bright clear. Otherwise, to make the appropriate adjustment (refer to burner instructions). Note: The oil pressure between 0.8 ~ 1.0Mpa, after a good tune, do not easily change, oil pressure is too high or too low have an effect on burner performance life. 5, check the pressure gauge pointer swing is smooth, with or without loosening stuck. 6, whether the discharge check valve is set at the set pressure steam: Pressure controller first maximum working pressure, a safety valve is adjusted to the set pressure higher than 0.05MPa, when the furnace pressure was raised to whether the exhaust pressure setting, if exhaust , pulling the safety valve a few times, and try again, if not enough to deal with safety valve to adjust. Pressure relief valve setting: boiler rated pressure + 0.03MPa. 7, check the electrical contacts of the operation: When the pressure is raised to the maximum working pressure (not exceed the rated working pressure), should stop burning, open the safety valve blowing off steam, the pressure to a minimum operating pressure (maximum operating pressure is generally lowest set to 0.10MPa), combustion burner should be restarted. Note: When the adjustment screw should slow, especially when the pointer approaches the end, otherwise, damage the screw off the wire.

February 21 this year, the Harbin Municipal People's Government issued the "blue sky Harbin win the Battle of three-year action plan to implement the program" (hereinafter referred to as the "Program"), as follows.

First, strictly control the total coal consumption

The county (city) should shoulder the main responsibility for control of the total coal consumption, according to the focus on the use of coal and clean use of principles, focusing on reduction of non-coal power, propulsion power and other clean energy alternative to coal and oil by 2020, coal accounting for the proportion of energy consumption compared to 2015 decreased by 1.5 percentage points or more.

Second, to strengthen control bulk coal

Actively promote the construction of biomass power generation. Enhanced geothermal energy exploration, development and utilization of resources to carry out detailed investigation and evaluation of geothermal energy, geothermal energy resources in the region to find out the distribution and exploitation potential. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem. By 2020, the proportion of non-fossil fuels in primary energy consumption of the city's total, compared with 2017 increased by 1 percentage point.

The main functional difference component of natural gas and low price 1t steam boiler thailand 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.

New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the boiler. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.
