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...
Safety accessories of the thermal oil heater include safety valves and bursting discs, stop valves, pressure gauges, etc.
The basic configuration of low nitrogen thermal oil heater system includes the following main parts:
1. Combustion system: including furnace, burner, ignition device, etc.
2. Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
3. Control system: complete with boiler control box.
4. Air-smoke system: refers to the s...
Raw water: refers to water that has not been disinfected and filtered, such as river water, stream water, well water, reservoir water, etc.
Feed water: refers to the chemical water delivered from deaerator to boiler by feed pump.
Make-up water: Make-up water for boiler is to make up the lost part or externally supplied part after completing a steam-water cycle, so that the boiler can always operate at a safe water level.
Recycling condensing water: When the heat energy of steam or hot water i...

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 mortar in the outer brick joints of the furnace wall can be ground into powder by hand without bonding, which indicates the mortar has been dried.
(2) Use a thermometer to insert 100mm from the outer wall. When the temperature reaches 50℃, it can last for 48h, and the outer wall temperature should be uniform.
(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...
