Our coal-fired boiler project, carried out in full swing everywhere, together with the relevant departments for coal-fired boiler users on schedule to complete the transformation of a certain intensity to give subsidies, so that this "green revolution" of the more fiery!
The use of gas-fired boiler, select the "air" is the key! Say good gas boiler, intelligent and efficient and environmentally friendly. Gas is actually a general word, liquefied natural gas, liquefied petroleum gas, city gas, etc., are collectively referred to as gas.
Attention should be paid to the following issues: The working temperature of boiler steel structure. The U. S. boiler code stipulates that the temperature of the load-bearing member shall not be greater than 315 ℃ after heating, because the yield strength of the steel decreases sharply due to the increase of the temperature. The fire resistance limit of steel columns, steel frames and steel frames without protective layer is only 15 minutes in < Code for Building Design Fire Protection >, that is to say, the steel structure in the fire will soon deform and fail in the fire. The fire resistance of the steel column and the steel beam occurs when the boiler room is on fire, and the fire resistance limit of the steel column, frame and frame is only 15 minutes. Therefore, the following requirements are required: (1) the laying of the boiler tubing road and the cable should leave the load-bearing parts; (2) in the event of fire, it is very important to organize the force to control the temperature of the load-bearing parts.
Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.

This method calculates boiler efficiency by using the basic efficiency formula-η=(Energy output)/(Energy input) X 100. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where,Online chat
Formula for Calculating Fuel Consumption of Steam Boiler 2019-01-22 11:08:41. When purchasing industrial steam boilers, customers pay more attention to the cost of steam boiler, especially the fuel consumption in operation costs. The following are the fuel calculation formulas for saturated steam boiler and superheated steam boiler.Online chat
Classification of Steam Heating Systems - Steam systems carries heat through pipes from the boiler to consumers as heat exchangers, process equipment etc. Condensate Generation in Cold Steam Pipes - Sizing of Steam Traps - When cold steam pipes are heated up they generate huge amounts of condensate that must be drained away from the pipeOnline chat
Aug 29, 2017 · Boiler Efficiency Calculation: a complete guide. Then certainly there is an optimum value of the air excess to obtain the best combustion efficiency. As an illustration, the optimum value of air excess to the combustion of natural gas is 5 to 10%, liquid fuel at the rate of 5 to 20%, and 15 to 60% for coal combustion.Online chat
Boiler Capacity - Steam boilers output can be expressed in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour Classification of Steam Heating Systems - Steam systems carries heat through pipes from the boiler to consumers as heat exchangers, process equipment etc.Online chat
Nov 24, 2016 · 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) Boiler Efficiency by Indirect Method : Where the efficiency is the difference between the losses and the energy input.Online chat
Heat Loss Calculation Application: Excellent when determining heat loss of a building as a whole. This calculation will help determine a boiler size for a home. This is to be used as an estimation. A detailed heat loss should be provided before a new boiler is installed. * Heating multipliers (H.M.) BTU/Hr based onOnline chat
boiler contains a safety valve that, when the pressure becomes too high due to blockage or overheating, releases the excess steam. Project Description Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar.Online chat
