Modular gas-fired boiler, according to the user's load and design needs, combines several independently operating module units into an integral boiler. By monitoring and calculating the changes of indoor and outdoor temperature and temperature of supply and return water, the computer automatic control system can control each level of modules, automatically adjust the number of modules to start and stop, make the output heat always match the actual required heat load, and ensure that each module ...
Boiler output refers to the maximum continuous output of the boiler under rated parameters (pressure, temperature) and certain efficiency. For steam boilers, it is called rated evaporation, and the unit is tons/hour; For hot water boilers, it is called rated heat production, and the unit is MW.
What are the main factors affecting the output of gas-fired boilers? According to the analysis of ZOZEN Boiler engineers, there are many reasons for the insufficient output of gas-fired boilers,
...
Different users have different requirements for boiler configuration. For example, some users need NOx emission less than 30mg/Nm3, and some users only need it less than 80mg/Nm3. The better auxiliary equipment configuration is used, the price of boiler will naturally rise.
Different users have different requirements for the configuration of the whole boiler system, and the brand and quantity of auxiliary machines also affect the price. The better the brand, the more expensive the price. For ex...
The boiler in the bathhouse provides hot water for bathing and heating, and it is an essential product in bathhouses. Generally, it is hot water boiler. With the elimination and banning of coal-fired boilers, many users choose energy-saving and environment-friendly gas-fired boilers. Then how much is a suitable gas-fired boiler?
First of all, we have to determine the boiler plan. Bathhouses mainly need to supply hot water and winter heating all the year round. There are two main options: one se...
The boiler drum is connected with downcomer and water wall to form a natural circulation loop. At the same time, the boiler drum receives the feed water from the economizer and delivers saturated steam to the superheater. Therefore, the boiler drum is the connecting hub of the three processes of heating, evaporation and overheating in the boiler.
When choosing the 80-ton gas-fired steam boiler, the price determines the customer's upfront investment cost, so it is as important as the quality. However, the price is not determined by a single factor, it is related to many aspects, the price of 80-ton gas-fired steam boiler will be different with different choices. Let’s talk about what are the main factors that affect the 80-ton gas-fired steam boiler?
(1) The furnace drying time depends on the shape, structure and humidity of the furnace. It takes 4 ~ 7 days for small low-pressure boilers and 10 ~ 15 days for heavy furnace walls.
(2) First, bake with wood, on the ash hopper of the room furnace and the grate of the chain furnace, use small fire for natural ventilation within 2 ~ 3 hours. When the temperature of combustion chamber rises, the ventilation capacity will be improved, and the flue damper can be turned down a little. It is best to k...
(1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified.
(2) All rotating devices, feed water pumps, condensate pumps, salt solution pumps, blowers and induced draft fans for coal conveying, combustion and ash removal are qualified for trial operation.
(3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
