difference water tube boiler vs fire tube
Methods and characteristics of steam difference water tube boiler vs fire tube water treatment
The steam boiler water treatment method has the boiler outside and the furnace also called the pot inside and outside the pot. Generally, for steam boilers and steam-steam boilers larger than 2t/h, the chemical water treatment outside the furnace should be adopted as far as possible, on the other hand, the steam boiler can only be treated with medicine in the furnace, but other means should be adopted to ensure the quality of water quality.
Design requirements for flue of fuel gas difference water tube boiler vs fire tube roomThe flue should be straight, airtight, less accessories and less resistance, horizontal flue should be laid to maintain more than 1% of the head-up arrangement, as far as possible to avoid the layout along the slope. 2. The flue and chimney of the fuel gas boiler room shall be constructed of steel or reinforced concrete, and the lowest point of the flue and chimney shall be provided with water sealed air and water drainage pipes. 3. The steel plate thickness of metal flue is generally 4-6 mm. When designing the flue, it should be equipped with sufficient reinforcement ribs to ensure the strength and stiffness requirements. 4. The thermal expansion of the flue should be compensated, the compensation amount should be calculated and the correct selection should be made. 5. Heat preservation measures and reliability of steel flue The fixation of the. 6. A boiler corresponding to a chimney should be used in a fuel-fired boiler room. When several boilers are required to share a flue or chimney, the ventilation and suction force of each boiler should be balanced. 7. The necessary thermal and environmental measurement points should be installed in the proper location when the flue is arranged. A single oil-fired boiler with a rated evaporation capacity greater than or equal to 20t/h or a single rated thermal power greater than or equal to 14MW must be fitted with a fixed instrument for continuous monitoring of smoke and SO2 emission concentrations in flue gas. 8. Where smoke easily gathers, and when multiple boilers share a chimney or a total flue, each fuel gas Explosion-proof doors shall be installed on the flue after the boiler, and the position of the explosion-proof doors shall be conducive to pressure relief, and shall be located in a proper position not to endanger the safety of personnel and before turning, when the explosion gas may endanger the safety of the operator. Pressure relief guide tubes should be installed on the explosion-proof device. 9. For some boiler rooms with long flue, the resistance should be calculated and the corresponding blower and induced fan (when there are induced fans) should be selected in order to ensure the smokeless flow. 10. The chimney should consider the corresponding anti-corrosion measures, the flue gas temperature at the outlet of the chimney should be 15 ℃ higher than the dew point temperature of the flue gas, and when the exhaust temperature is lower than the dew point temperature of the flue gas, effective measures should be taken to prevent it. The smoke is poured upside down.
Central heating hot water difference water tube boiler vs fire tubes for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.
In natural gas fuel for example, the high heat of about 9500kcal / m³, low heat generation of about 8600kcal / m³, a difference of about 900kcal / m³, 11% of low calorific value, choosing condensing difference water tube boiler vs fire tube compared to the conventional type boiler reduce operating costs of gas around 11%. (High and low calorific details, see) Second, condensing boilers more environmentally friendly. Compared with conventional coal-fired boiler, condensing boilers are generally clean and environmentally friendly natural gas as fuel, the exhaust gas boiler having a much reduced, alleviating urban air emissions of sulfur oxides, nitrogen oxides, dust and other harmful substances, green pioneer in environmental protection boiler products.
