List of calorific values for different fuels
Fuel calorific value is an important parameter for calculating boiler fuel consumption. Knowing this data can help customers select more economical boiler products when purchasing boilers. In general, the fuel used in boilers can be broadly classified into three categories: solid fuels, liquid fuels, and gaseous fuels.
In addition to steam, hot water should be used for heating, ventilation and hot water supply. Its main advantages are: 1) Hot water heating can save a lot of fuel (compared to steam), about 20% 40%. Because it has no condensation water and secondary evaporation loss. Secondly, the heat loss of hot water heating pipe is small. Steam leakage loss of steam heating pipe is large. Steam china best boiler factorys require continuous and periodic discharge, while hot water boilers require only a small amount of periodic discharge. Finally, hot water heating can adjust the quality of hot water flexibly according to the change of outdoor ambient temperature, which can not only save fuel but also ensure the quality of heating.
2) the maintenance cost of hot water heating system is lower than that of steam heating system. It has been proved that the maintenance cost of hot water heating system is only 1 / 3 of steam heating system, and the maintenance personnel can be reduced by half accordingly.
3) Hot water heating has a large thermal radius, which can reach tens of kilometers, while steam heating is limited by the loss of pipe resistance, which is usually only 2 ~ 3 kilometers.
4) High temperature water heating is suitable for the development of regional heating industry. The use of regional central heating can not only save a lot of fuel, but also reduce the pollution of the boiler to the atmospheric environment.
Recently, the China Engineering Co., Ltd. hot and fast Boiler Co., Ltd. signed a strategic cooperation agreement, both sides of the trust based on good, long-term development strategy for the two sides to consider, powerful alliances, work together to open up the market to achieve a win-win. China Thermal Engineering Co., Ltd. is a consulting, design, general contracting, investment, development, management operations in one, involving multiple areas of integrated enterprise. Huare company has a municipal utility industry thermal qualification, professional qualification of city gas engineering, construction industry, construction qualification, design pressure pipeline GB1, GB2, GC2 qualifications, municipal utilities (gas and heating) consulting qualification, by continuously strengthen the quality management, establish a sound quality assurance system, and successfully passed the ISO9001 quality system certification, occupational health and safety management system certification, environmental management system certification.
Design requirements for flue of fuel gas china best boiler factory 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.
