Gas-fired dzl industrial coal straw fired steam boiler for eps and gas steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas steam boiler and gas steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answer the same model as compared to steam boilers or gas steam boiler energy conservation, we can roughly be calculated next-ton per hour boiler full load of work to 150-160Kg coal according to the market value of fuel gas and gas to about 80m3 . A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.

Advancing the ignition point of coal, 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. 2. The air supply and reasonable regulation. In Grate, vibration stove, oven and forth, depending on the characteristics of the combustion process, reasonable air, to promote combustion furnace is very important. As the chain furnace, with grate the fuel is kept in motion, occur sequentially ignition, combustion, burn various stages. Along the longitudinal direction of the combustion grate stages, the partition, the amount of air required in the grate longitudinal direction is different. In the preheating zone of the head and the tail of burnout grate stage, small air requirement in the middle stage of combustion grate, the air amount required.

January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.

Prior to 2017, the total removal of Harbin urban built-up area of ​​small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.

According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.

Why horizontal gas dzl industrial coal straw fired steam boiler for eps to run under negative pressure? Horizontal Gas-fired steam boilers are generally negative pressure operation, if the pressure is running high temperature flue gas will cause the furnace to burn jet furnace walls and insulation, but also endanger the safety of operating personnel , the negative pressure is not too large, generally -10 ~ -30Pa, small oil-fired boiler is generally because there is no draft fan for the combustion positive pressure. For improving the thermal efficiency of the boiler has the following methods: a low pressure industrial boiler manufacturers has been designed in consideration of the problem of overheating efficiency, device, or change from the flue gas energy aspects is not possible and thus the best energy boiler operation starting from the (here not On the recovered water of vapor condensation). According to statistics survey, the current design of the thermal efficiency of domestic low-voltage industrial boilers is generally 70 to 90%, generally the actual operation of the thermal efficiency of about 60 to 80%, some even below 50%, a small low pressure industrial boilers as long as the operation, maintenance properly, design can achieve the thermal efficiency of the boiler manufacturers. I think the management and operation of the boiler should pay attention to the following points: First, to monitor the boiler exhaust gas temperature. Usually the largest boiler flue gas heat loss is a loss, so control the boiler flue gas temperature is very important, general industrial boilers low pressure gas (mainly refers to less than 10 tons of boiler and pressure of 1.6MPa, the same below) of the exhaust gas temperature is 150 ~ 180 ℃, oil-fired boiler exhaust gas temperature is 210 ~ 240 ℃, when the exhaust gas temperature is too high to find the cause and timely elimination. Causes of high temperature exhaust gas boiler are: a chamber negative pressure is too high, short-circuiting flue gases, the heat pipe 3 soot is too thick, too thick scale pan 4, etc., oil-fired boiler exhaust gas temperature is too high reasons : 1 air not adjusted oil, the oil is not completely burned in the chimney secondary combustion occurs aft, 2 soot too, the need for timely cleaning, the flue gas short circuit 3, 4 is too thick scale, etc. second, the control of boiler blowdown rate. General industrial boiler blowdown rate controlled at 5 to 10%, in the pot of water to ensure that qualified (mainly total alkalinity and pH) under the premise of boiler blowdown rate as low as possible, the sewage to adhere to the "ground row, row less, uniform discharge "principle. Third, the maintenance of good boiler furnace wall insulation. Boiler heat loss is also a relatively large heat losses, now the boiler manufacturers in the manufacturing and design has been well thought out, so we do not need to change, we just trying to be difficult to maintain. Outsourcing surface temperature generally does not exceed the boiler 50 ℃, such as too high will have to find out the reasons, timely elimination. Boiler insulation should always be kept dry for gas boilers, pressure must not run long, or easy to damage the coal furnace wall and gate and so on. Fourth, adjust the ratio of fuel and air volume, complete combustion of the fuel as possible. Small boilers generally do not have the amount of wind testing instruments, we can only go by experience adjustment. For oil-fired boiler, the normal combustion flame was yellow-white, non-glare, flame stability, no visible smoke chimney; for gas boiler, the normal combustion flame as a light yellow, no visible smoke stack, substantially cinder burn coal particles as uniform as possible. Fifth, there must be complete boiler water treatment. Complete boiler water treatment and water quality testing can maximize prevent boiler scaling and correct guidance of the sewage, but it did not do a lot of small boilers, companies usually do not pay attention.
